The consignment number in India Post is a unique 13‑character tracking ID printed on your receipt that lets you track and manage your parcel (Speed Post, Registered, etc.) throughout its journey.

What exactly is a consignment number?

  • It is a unique alphanumeric code assigned to every postal article that is booked with tracking (like Speed Post, Registered Parcels, EMS, etc.).
  • India Post’s standard format is 13 characters: two capital letters, nine digits, and two capital letters at the end (for example: EK403807171IN).
  • You need this number to:
    • Track status online or via SMS
    • Raise a complaint or inquiry about delay/loss
    • Prove booking/acceptance of the article

How the format works (simple breakdown)

A typical India Post consignment number looks like: EK123456789IN.

  • First 2 letters → service type (and sometimes origin info)
    • E / EM: Speed Post / Express Mail Service
* CP: Parcel (often registered/commerce parcel)

* Other prefixes exist for different services (e.g., passport, registered letter, etc.).
  • Next 9 digits → computer‑generated unique number for that article.
  • Last 2 letters → usually “IN”, indicating India as the originating country.

So if you see something like EM123456789IN , it is an EMS/Speed‑type consignment booked in India, with that specific numeric ID.

Where do you find the consignment number?

  • On the physical receipt given at the post office at the time of booking.
  • On the shipping label stuck on the parcel or envelope.
  • In SMS or email alerts, if you provided a mobile number or email while booking.

It is usually clearly printed next to “Consignment No.”, “Article No.”, “Tracking No.” or similar wording.

What is it used for in practice?

  • Online tracking :
    • Go to the official India Post “Track Consignment” page and enter the consignment number to see current status, location scans, and delivery events.
  • SMS tracking (where supported):
    • Some guides mention sending an SMS in the format like “POST TRACK ” to designated numbers (e.g., 166 or 51969), to receive status by SMS.
  • Customer support & complaints:
    • If you lodge a complaint about delay, damage, or non‑delivery, the consignment number is the key reference.

How fast does tracking update?

  • Scan events (e.g., “Item booked”, “In transit”, “Out for delivery”, “Delivered”) are updated periodically in the system.
  • Some recent explanations mention that it may take 2–4 working days after booking for full tracking details to start reflecting reliably, especially for certain routes.

Mini FAQ

Is consignment number the same as tracking number?

Yes. For India Post services with tracking, “consignment number”, “article number”, and “tracking number” are used interchangeably.

Do ordinary (unregistered) letters have a consignment number?

No. Only registered, Speed Post, EMS, and similar trackable services are assigned a consignment number.

What if my consignment number shows no record?

  • Double‑check you typed all 13 characters correctly.
  • Wait a bit if it’s just been booked, as the system may not have updated yet.
  • If it’s been several days and still no record, contact India Post with the physical receipt.

In simple words: the consignment number in India Post is your parcel’s unique “passport number” that lets you see where it is, prove it was booked, and get help if anything goes wrong.
