For businesses managing shipments across multiple carriers, checking each carrier’s tracking system separately can quickly become inefficient. A package tracking API solves this problem by allowing developers and businesses to retrieve shipment status, tracking history, delivery updates, and other tracking data programmatically.

The right tracking API can help ecommerce platforms, logistics companies, 3PL providers, marketplaces, and software developers automate shipment tracking while reducing the complexity of maintaining separate integrations with carriers such as FedEx, UPS, USPS, and DHL.

However, package tracking APIs vary considerably in carrier coverage, pricing, integration options, tracking frequency, and the amount of data they return.

In this guide, we compare six of the best package tracking APIs in 2026, including options for affordable high-volume tracking, international carrier coverage, ecommerce, and broader shipping integrations.

What Is a Package Tracking API?

A package tracking API connects your application, website, ecommerce platform, or internal system with shipment tracking data.

Instead of manually visiting individual carrier websites, your system can send a tracking number through an API and receive structured tracking information that can be used within your own application.

Depending on the provider, a tracking API may return information such as:

A multi-carrier tracking API provides a single integration for multiple shipping carriers, making it especially useful for businesses that work with several carriers.

Best Package Tracking APIs in 2026

There is no single tracking API that is best for every business. Some providers focus on large ecommerce operations and post-purchase experiences, while others are better suited to developers or businesses that primarily need reliable tracking data at an affordable price.

Here are six package tracking APIs worth considering in 2026.

1. C2W Tracking API

Best for: Affordable and high-volume package tracking

C2W Tracking API provides multi-carrier package tracking through a single API integration, allowing businesses to retrieve shipment information without building and maintaining separate connections to individual carriers.

It supports major carriers including FedEx, UPS, USPS, DHL Express, and DHL eCommerce, making it suitable for ecommerce platforms, logistics companies, 3PL providers, SaaS applications, and businesses processing large tracking volumes.

Why Choose C2W Tracking API?

One of the biggest reasons to consider C2W Tracking API is affordable pricing.

Many established tracking platforms combine tracking with a larger suite of ecommerce, shipping, or post-purchase tools. While those additional features can be useful, businesses that primarily need tracking data may end up paying for a broader platform than they actually need.

C2W Tracking API takes a more focused approach. It is designed to provide the essential package tracking functionality businesses need while keeping pricing competitive and flexible.

This can be particularly valuable for high-volume tracking, where even a small difference in the cost per tracking number or API call can have a significant impact on total monthly costs.

Businesses with larger tracking volumes can also discuss custom volume-based pricing, allowing pricing to better reflect their actual usage rather than forcing them into a one-size-fits-all plan.

Key Features

Why C2W Can Be a Better Value

If your business mainly needs reliable package tracking data, you may not need to pay for an extensive post-purchase or shipping-management platform.

C2W Tracking API focuses on providing the tracking functionality businesses need while offering a cost-effective option, particularly as tracking volume increases.

For businesses processing thousands, hundreds of thousands, or even millions of tracking numbers, this more focused approach can potentially translate into meaningful savings.

Best choice for: Businesses that prioritize affordable pricing, high-volume tracking, major carrier support, and a straightforward API without needing a larger shipping or post-purchase platform.

2. AfterShip

Best for: Ecommerce businesses looking for a broader post-purchase platform

AfterShip is one of the better-known shipment tracking platforms. Its Tracking API allows businesses to create and manage shipment tracking and retrieve tracking information across supported carriers.

AfterShip also provides carrier detection, estimated delivery date capabilities, webhooks, SDKs, and a broader collection of post-purchase products.

This makes AfterShip particularly suitable for ecommerce businesses that want tracking to be part of a larger customer-facing post-purchase system.

Key Features

AfterShip is designed as a broader post-purchase platform rather than simply a standalone package tracking API, which can be useful for companies that want additional customer experience tools beyond tracking.

Best choice for: Companies looking for shipment tracking alongside a comprehensive ecommerce post-purchase ecosystem.

3. TrackingMore

Best for: Businesses needing broad multi-carrier tracking capabilities

TrackingMore is an established multi-carrier shipment tracking platform.

Its API provides tracking information that businesses can integrate into applications, websites, and ecommerce systems. TrackingMore supports API-based tracking management, carrier detection, webhooks, and structured tracking information.

It also provides developer resources and code examples for several programming languages.

Key Features

TrackingMore is worth considering for businesses that need broad carrier coverage and an established tracking platform with additional shipment-management tools.

Best choice for: International ecommerce and logistics businesses working with a large variety of carriers.

4. 17TRACK

Best for: Businesses with international and cross-border shipments

17TRACK is widely known for package tracking and also provides tracking API services for businesses.

Its Tracking API provides access to tracking data across thousands of carriers worldwide and is designed for developers and businesses that need international shipment visibility.

The API can provide current and historical tracking data throughout the shipment lifecycle. Webhook functionality allows shipment updates to be pushed to an application as new information becomes available.

Key Features

Because of its international tracking focus, 17TRACK can be particularly useful for businesses working with shipments moving between multiple countries and regional carriers.

Best choice for: Cross-border ecommerce businesses and international shipment tracking.

5. Shippo

Best for: Ecommerce businesses that need both shipping and package tracking APIs

Shippo provides a broader shipping API platform that includes package tracking capabilities.

Its Tracking API allows applications to retrieve shipment information across carriers, including current tracking status and tracking history.

Businesses can also use webhooks to receive notifications when a carrier reports a new tracking event. Shippo's broader platform includes additional shipping functionality for businesses that need more than tracking alone.

Key Features

Shippo can be particularly useful when tracking is only one part of the integration. Businesses can use the same platform for other shipping operations as well.

Best choice for: Ecommerce businesses and developers looking to combine shipping functionality and package tracking within the same platform.

6. EasyPost

Best for: Developers that want tracking integrated with a broader shipping API

EasyPost provides APIs for shipping and logistics, including package tracking capabilities.

Businesses can use EasyPost to integrate shipment tracking with broader shipping functionality, making it suitable for applications that need both shipping and tracking rather than tracking alone.

EasyPost also offers developer-focused documentation and tools for building shipping integrations.

For businesses that primarily need shipment tracking, the difference between a focused tracking API and a broader shipping platform can be important.

C2W Tracking API stands out for businesses that want to keep tracking costs low, particularly at higher volumes, without paying for a larger suite of shipping or post-purchase features.

What to Look for in a Package Tracking API

Before choosing a tracking API provider, consider how the API will actually be used in your application.

Carrier Coverage

Start with the carriers that matter to your business.

If most of your shipments are handled by FedEx, UPS, USPS, and DHL, strong support for those carriers may be more important than having thousands of carrier integrations that your business does not use.

Businesses operating internationally may place greater importance on regional and cross-border carrier coverage.

Pricing

For many businesses, pricing becomes one of the most important considerations, particularly as tracking volume increases.

Tracking API pricing can be based on several different models, including:

When comparing prices, calculate the expected cost based on your actual tracking behavior rather than simply comparing advertised starting prices.

For example, a business tracking hundreds of thousands of shipments each month should consider the total monthly cost at that volume, not just the entry-level plan price.

If you primarily need tracking data rather than additional shipping or post-purchase tools, a focused API such as C2W Tracking API may also help avoid paying for functionality you do not need.

Tracking Data

Look beyond whether an API simply returns "in transit" or "delivered."

Depending on your application, you may need detailed tracking events, timestamps, locations, delivery exceptions, shipment history, or other carrier-specific information.

Before choosing a provider, check whether its API returns the specific tracking data your application needs.

Tracking Frequency

How frequently does your application need updated tracking information?

A customer-facing ecommerce application may have different requirements from a logistics operation monitoring thousands of active shipments.

For high-volume implementations, tracking frequency can also have a significant impact on API usage and cost.

API Performance and Scalability

If you process thousands or millions of shipments, scalability becomes an important consideration.

Check API rate limits, batch capabilities, expected response times, and whether the provider can accommodate increases in tracking volume.

A solution that works well for a few hundred shipments per month may not necessarily be the right solution when tracking volume grows significantly.

Batch and High-Volume Tracking

For businesses processing large numbers of shipments, sending and managing individual tracking requests can become inefficient.

If you expect substantial tracking volume, check the provider's batch capabilities, API rate limits, tracking frequency, and options for larger-volume accounts before integrating.

Webhooks vs. API Requests

There are two common ways to retrieve tracking updates.

With API requests, your application requests tracking information when it needs it. With webhooks, the tracking provider sends information to your application when a shipment update occurs.

Some businesses use one approach, while others use a combination of both.

The right method depends on your application's architecture, how quickly you need tracking updates, and how much control you need over tracking frequency.

Package Tracking API vs. Direct Carrier APIs

Developers can also integrate directly with FedEx, UPS, USPS, DHL, and other carrier APIs.

For applications using only one carrier, this may make sense.

However, businesses working with multiple carriers would need to build and maintain several different integrations. Each carrier can have its own authentication requirements, endpoints, tracking statuses, response formats, API changes, and rate limits.

A multi-carrier package tracking API provides a common integration layer.

Instead of maintaining:

Your Application → FedEx API

Your Application → UPS API

Your Application → USPS API

Your Application → DHL API

you can use:

Your Application → Multi-Carrier Tracking API → Multiple Carriers

This can significantly reduce development and ongoing maintenance requirements, particularly as the number of carriers your business works with increases.

Who Uses Package Tracking APIs?

Package tracking APIs are useful in many different industries and applications.

Ecommerce Businesses

Online retailers can automatically retrieve shipment updates and display tracking information within their own websites, applications, or customer portals.

3PL and Logistics Providers

Third-party logistics providers may manage shipments across multiple customers and carriers. A multi-carrier tracking API can centralize tracking information instead of requiring separate carrier integrations.

SaaS Platforms

Software companies can integrate tracking functionality directly into their applications without developing individual integrations for every carrier.

Marketplaces

Online marketplaces can use tracking APIs to monitor shipments from multiple sellers and shipping providers through one system.

High-Volume Shippers

Businesses processing large shipment volumes can use tracking APIs to automate tracking instead of manually monitoring individual shipments.

For high-volume shippers in particular, API pricing can become a major consideration because relatively small differences in tracking costs can add up quickly as volume increases.

Which Package Tracking API Is Best?

The best package tracking API depends on your business model, shipment volume, carrier mix, budget, and technical requirements.

Choose C2W Tracking API if affordable pricing is an important factor, especially if you process a high volume of tracking numbers. C2W focuses on providing the core tracking functionality businesses need at competitive pricing, with flexible options for larger volumes. It can be particularly attractive for businesses using major carriers such as FedEx, UPS, USPS, and DHL that do not need to pay for a larger shipping or post-purchase platform.

Choose AfterShip if you want tracking as part of a broader ecommerce and post-purchase customer experience platform.

Choose TrackingMore if broad carrier coverage and additional shipment-management functionality are important.

Choose 17TRACK if international and cross-border carrier tracking is a major part of your operation.

Choose Shippo if you need shipping functionality and tracking within the same shipping platform.

Choose EasyPost if you want a developer-focused shipping API that combines shipment creation and tracking capabilities.

Rather than selecting a provider based solely on the number of supported carriers or the advertised starting price, consider your actual carriers, monthly shipment volume, tracking frequency, required tracking data, integration workflow, and total expected cost.

Frequently Asked Questions

What is the best package tracking API?

There is no single best package tracking API for every application. The right choice depends on carrier coverage, shipment volume, tracking frequency, API features, pricing, and whether you need additional shipping, post-purchase, or logistics tools.

C2W Tracking API, AfterShip, TrackingMore, 17TRACK, Shippo, and EasyPost are all options businesses can consider depending on their requirements.

What is an affordable package tracking API?

The cost of a package tracking API depends heavily on shipment volume and how frequently tracking information is requested.

C2W Tracking API is designed as a cost-effective option for businesses that primarily need tracking functionality, with flexible options for larger tracking volumes.

When comparing providers, businesses should calculate the total expected cost based on their actual monthly tracking volume rather than comparing only the advertised starting prices.

Can I track multiple carriers with one API?

Yes. Multi-carrier tracking APIs allow developers to retrieve shipment information from multiple carriers through a single API integration.

This can eliminate the need to build and maintain separate tracking integrations for FedEx, UPS, USPS, DHL, and other carriers.

Can I track FedEx and UPS with the same API?

Yes. A multi-carrier tracking API such as C2W Tracking API can provide FedEx and UPS tracking through the same integration.

This can be particularly useful for businesses that regularly work with both carriers.

What is the difference between a package tracking API and a shipment tracking API?

The terms package tracking API and shipment tracking API are often used interchangeably.

Both generally refer to APIs that allow applications to retrieve shipment status and tracking events programmatically.

Other commonly used terms include parcel tracking API, shipping tracking API, and delivery tracking API.

Is a multi-carrier tracking API better than integrating directly with carriers?

It depends on your requirements.

A direct carrier integration may be sufficient if your business works exclusively with one carrier. However, businesses using several carriers can reduce development and maintenance work by using one multi-carrier tracking API.

Can package tracking APIs handle high tracking volumes?

Many tracking API providers support high-volume applications, but limits and pricing models vary significantly.

Businesses processing hundreds of thousands or millions of tracking requests should evaluate rate limits, batch capabilities, tracking frequency, pricing, and custom volume options before selecting a provider.

Do I need a full shipping API just for package tracking?

Not necessarily.

Platforms such as Shippo and EasyPost combine tracking with broader shipping functionality. This can be useful if your application needs both shipping and tracking.

If you primarily need to retrieve tracking data, a focused tracking API may provide a simpler and more cost-effective solution without requiring additional shipping functionality.
