AfterShip vs. EasyPost vs. 17TRACK vs. TrackingMore vs. Ship24 vs. lastscanned (2026)

When evaluating a multi-carrier package tracking API in 2026, engineering and operations teams typically compare six platforms: lastscanned, AfterShip, EasyPost, 17TRACK, TrackingMore, and Ship24.

Most legacy tracking APIs were architected around asynchronous background queues: you POST a tracking number to register a tracker in their database, receive an empty PENDING response, and wait seconds or minutes for an inbound webhook before your application knows where the parcel is. Even when you only want to answer a customer's live "Where is my order?" question in a chat widget or AI agent, you are forced to manage state and pay enterprise monthly minimums.

lastscanned combines both models in one API across 542 carriers:

1. Synchronous single-GET lookups (GET /v1/track/:number and batch GET /v1/track?numbers=...) that return the normalized status and full chronological scan history immediately in the HTTP response.
2. Push Watches and Webhooks (POST /v1/watches) that also return the live tracking result immediately in the creation response, then automatically re-check the parcel on an adaptive schedule (15 min when out_for_delivery, 30 min on exception, 1 hr in transit, 2 hr on label_created) and send signed webhook events (tracking.updated, watch.ended) in either lastscanned's native JSON format or drop-in 17TRACK v2 webhook format ("format": "17track").

Where Each Platform Wins (and Where Teams Switch to lastscanned)Copy Anchor Link

1. AfterShip vs. lastscannedCopy Anchor Link

• Why teams run into friction with AfterShip: AfterShip restricts REST API and webhook access to its $59/month Premium tier (and higher enterprise tiers), with $0.08/shipment overages. Every tracking lookup requires creating a persistent tracker resource first, which returns an empty event list until AfterShip's background crawler finishes polling the carrier.
• Why developers switch to lastscanned: With lastscanned, GET /v1/track/:number returns the live carrier timeline synchronously in a single request, and POST /v1/watches returns that exact same live result on creation while scheduling automatic background re-checks at no extra charge. At $4.99/month for 1,000 unique tracking numbers ($0.015 per additional number), lastscanned cuts monthly tracking API spend by over 90% for growing merchants and SaaS tools.

2. EasyPost vs. lastscannedCopy Anchor Link

• Why teams run into friction with EasyPost: Following EasyPost's February 2026 pricing update, merchants face $0.08 per shipping label above 3,000 labels/month, a 3.75% credit card wallet top-up fee (or 0.50% ACH fee), and $0.01–$0.03 per standalone tracking number. Worse, EasyPost's carrier coverage is focused on traditional label-generation carriers, leaving major blind spots across cross-border consolidators (Yanwen, 4PX, Cainiao, YunExpress, CNE, SunYou) and regional last-mile couriers (UniUni, SpeedX, GOFO, Better Trucks).
• Why developers switch to lastscanned: Even if you buy labels through Pirate Ship, Shippo, or EasyPost, pointing your post-purchase tracking and WISMO AI agents at lastscanned gives you 542 carriers, automatic cross-border last-mile handoff extraction ("Handed to UniUni as UUS5BM1269395824723"), and predictable unique-number billing without wallet top-up fees.

3. 17TRACK vs. lastscannedCopy Anchor Link

• Why teams run into friction with 17TRACK: 17TRACK's API requires calling /track/v2.2/register before querying /gettrackinfo, meaning your first call for an unregistered number returns zero scan events. On the storefront side, linking customers to 17TRACK exposes them to third-party display ads, while 17TRACK's numeric carrier codes (100003, 21051, 190094) require maintaining a separate lookup table.
• Zero-rewrite migration to lastscanned: lastscanned supports 17TRACK's exact webhook payload and signature verification out of the box. Run:

  Copy Text

  curl -X PUT https://api.lastscanned.com/v1/webhook \
    -H "Authorization: Bearer $LASTSCANNED_KEY" \
    -H "Content-Type: application/json" \
    -d '{"url": "https://example.com/hooks/tracking", "format": "17track"}'

  Every watch update arrives as TRACKING_UPDATED with 17TRACK's track_info object and sign header (sha256(rawBody + "/" + secret)), while POST /v1/watches gives you the first tracking result synchronously in the response. See Migrating from 17TRACK for the complete side-by-side mapping.

4. TrackingMore & Ship24 vs. lastscannedCopy Anchor Link

• Why teams run into friction with TrackingMore and Ship24: Ship24 splits its pricing between an asynchronous per-shipment plan ($39/mo) and a synchronous per-call plan ($99/mo), where polling the same package 15 times consumes 15 credits. TrackingMore's lower tiers restrict real-time synchronous endpoints and webhook throughput.
• Why developers switch to lastscanned: On lastscanned Pro ($4.99/mo), every lookup is synchronous, every re-poll of the same tracking number within your billing period is free, and watching a number via POST /v1/watches counts as just one unique number regardless of how many background re-checks (15 min to 2 hr intervals) occur until delivery.

Code Comparison: Synchronous GET + Instant-Result WatchesCopy Anchor Link

// 1. On-demand synchronous lookup (WISMO chatbot, order status page, CLI)
const res = await fetch("https://api.lastscanned.com/v1/track/1Z54V8630394427740", {
  headers: { Authorization: `Bearer ${process.env.LASTSCANNED_API_KEY}` },
});
const pkg = await res.json();
console.log(pkg.carrier, pkg.status, pkg.estimatedDelivery);

// 2. Create a background Watch (returns the live result immediately AND pushes webhooks on change)
const watchRes = await fetch("https://api.lastscanned.com/v1/watches", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.LASTSCANNED_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    trackingNumber: "UUS5BM1269395824723",
    metadata: { orderId: "ORD-90412", customerEmail: "buyer@example.com" },
  }),
});
const watch = await watchRes.json();
// watch.result -> immediate normalized TrackingResult (no waiting for a first webhook!)
// Subsequent status changes POST signed `tracking.updated` events to your webhook URL for free.
