India Post Consignment Number: Complete Tracking Guide 2026
An India Post consignment number is the unique 13-character code printed on every Speed Post receipt, and it is the single key to tracking a parcel from booking to delivery. Each scan, transfer, and status update in India Post's system is tied to this one identifier.
Beyond tracking, the number is proof that an item was sent, the reference for any complaint, and the documentation needed for an insurance or compensation claim. For a postal network serving more than 1.4 billion people, it is what keeps an individual parcel from disappearing into the system.
This guide explains what the consignment number is, how to decode it, where to find it, every way to track a package, what the status messages mean, and how to resolve the most common problems.
What is an India Post consignment number?
The consignment number is a unique 13-character code assigned to every Speed Post article at the moment of booking. It follows a fixed structure: two capital letters, then nine computer-generated digits, then two more capital letters — for example, EK403807171IN.
The nine middle digits are randomly generated and unique, so no two parcels ever share a number. If a code does not match this exact 13-character pattern, it has likely been copied down incorrectly and should be checked against the receipt.
This structure is what lets every scan along the journey attach to the right parcel. From the moment of booking through sorting, transit, and final delivery, the number is the thread that connects each update, which is why an accurate copy of it matters more than any other detail on the receipt.
What each part of the number means
Every segment of the 13-character code carries meaning, which makes it easy to verify at a glance. The table below decodes a sample number, EK403807171IN.
Segment | Example | What it indicates |
|---|---|---|
1st letter | E | Service type (E = Speed Post) |
2nd letter | K | State of booking (K = Karnataka) |
9 middle digits | 403807171 | Unique computer-generated identifier |
Last 2 letters | IN | Country code (India) |
The first letter signals the service: E for Speed Post, R for registered or insured articles, C for courier items, and EM for international Express Mail Service. The second letter maps to the booking state, and the final IN denotes India on domestic Speed Post.
Knowing the pattern is a quick error check. If a number meant to be a Speed Post article does not start with E, or does not end in IN for a domestic parcel, it is worth re-reading the receipt before assuming a tracking problem, since a single mis-keyed character is the most common reason a valid parcel appears untraceable.
Where to find the consignment number
The consignment number appears in at least 4 common places, so a lost receipt is rarely the end of the trail. The most direct source is the Speed Post receipt, where it is printed on the second line, usually labelled "Consignment No." or "Article ID," and recorded against the booking on the India Post system.
For online bookings, the number arrives by email confirmation and by SMS to the mobile number given at booking. When a seller ships via India Post, it also appears in the order's shipment details on platforms such as Amazon India or Flipkart.
A practical habit is to screenshot the number as soon as it arrives and, when sending to someone else, to share it with the recipient immediately so they can track the parcel themselves.
How to track an India Post package
India Post offers 4 ways to track a consignment, so users can pick whichever is most convenient. All of them need the 13-character number, and all draw on the same underlying system, so the status shown is consistent across them.
The official website
The primary method is the Track & Trace tool on the India Post website. Entering the 13-character number, completing the CAPTCHA, and selecting Search returns the current location, every dated scan, and the delivery status, usually in seconds.
SMS tracking
SMS tracking works without internet access and is useful on the go. India Post's own instruction is precise:
"To track the status of an article, send SMS 'POST TRACK <13-digit article number>' to 166 or 51969." (India Post.)
All letters must be capitals, since the SMS is case-sensitive. India Post also sends free SMS updates at booking and delivery to the registered mobile number.
The Postinfo app
India Post's official Postinfo app, available for Android and iOS, lets users track multiple articles at once, save frequent numbers, and receive push notifications. Several reputable third-party trackers also cover India Post for users who want a single dashboard across couriers.
What the tracking statuses mean
India Post uses a consistent set of status messages, and knowing them shows whether a parcel is on track or needs action. The table below summarises the main ones in the order they typically appear.
Status | What it means |
|---|---|
Item Booked | Accepted into the system; appears within ~2–3 hours of booking |
Item Received / Bagged | Arrived at a sorting facility and grouped for dispatch |
Item Dispatched | In transit between facilities (often 1–3 days) |
Out for Delivery | With the delivery agent; expected the same day |
Item Delivered | Handed over; usually shows the recipient's name and time |
Attempted Delivery | Delivery failed; another attempt the next working day |
Returned to Sender | Undeliverable after repeated attempts; sent back |
An "Available for Collection" status means the parcel is waiting at the local post office, typically after failed delivery attempts, and must be collected within a set window before it is returned.
Reading these statuses in sequence is the simplest way to anticipate delivery. Once a parcel shows "Out for Delivery" in the morning, it usually arrives the same day, so it is worth ensuring someone is available at the address and has identification ready for items that require a signature.
Common tracking problems and fixes
Most tracking issues fall into a handful of patterns with straightforward fixes. An "invalid number" error usually means a typo — zeros versus the letter O, ones versus capital I — or that a just-booked item has not synced yet, in which case waiting 2–3 hours and retrying resolves it.
No updates for 24–48 hours often reflects a parcel held at a sorting hub or missed scans during peak periods, and usually clears on its own. If a status is stuck longer, or if tracking shows "Delivered" but nothing was received, the next step is to contact India Post customer care on 1800 11 2011 or the delivery post office and file a complaint the same day.
Rural and remote destinations can show fewer scans than metro routes, so gaps between updates are normal there and not a sign of a lost parcel. Acting quickly matters most for a false "Delivered" status, because raising it the same day gives the post office the best chance of tracing the handover while the delivery agent's record is current.
How to recover a lost consignment number
A misplaced number can be recovered through about 5 routes, the most reliable being the booking post office. Staff can retrieve it from their system using the booking date, sender and recipient names, and the phone number used — ideally within a few days of booking, while records are fresh.
Other routes include searching email and messaging apps for "India Post," "Speed Post," or "consignment," checking the e-commerce order's invoice, or asking the recipient, since the number is often written on the delivery slip or the package itself. Digital payment records help by pinpointing the exact booking time even though they do not show the number directly.
The recipient is often the fastest source once a parcel is in transit or delivered. Because the number is shared at booking by SMS and email, the original sender frequently still has it even when the physical receipt is gone — making a quick message to the other party worth trying before a trip to the post office.
Why the consignment number matters beyond tracking
The consignment number serves at least 3 purposes beyond locating a parcel. It is accepted as proof of mailing for legal notices, applications, and business records, creating an audit trail of when an item was sent.
It is also mandatory documentation for any insurance or compensation claim on insured items, so the original receipt should be kept with the insured amount marked. And it is the primary reference for filing complaints — online, by phone on 1800 11 2011, or at a post office — which speeds up resolution considerably.
For businesses that ship through India Post, passing the consignment number to customers is also a mark of professionalism. Sharing it at dispatch, and the tracking link with it, reduces "where is my order" queries and builds trust, while giving the business its own audit trail for every shipment.
India Post versus private couriers
India Post's biggest advantage is reach, built on the world's largest postal network.
"India Post operates more than 154,000 post offices, the largest postal network in the world." (Government of India postal data.)
That network serves more than 19,000 PIN-code areas, including remote regions private couriers often skip, usually at lower cost. Its SMS tracking is free, and cash on delivery and government backing add reliability for official documents, drawing on the official network detailed on the India Post portal.
Private couriers typically offer more frequent scan points, faster system updates, and more polished interfaces, which suit time-critical urban shipments. The practical rule: India Post for affordability, rural reach, and official mail; private couriers for guaranteed, time-bound urban delivery.

Frequently asked questions
How many characters is an India Post consignment number?
It is 13 characters: two capital letters, nine digits, and two capital letters (for example, EK403807171IN). The first letter shows the service and the last two (IN) the country.
