A valid PIN is only the first check

Updated 27 September 2026

Before dispatching a parcel, separate the identity of the destination from the delivery service you intend to buy. A postal code, a courier office and a verified delivery route answer different questions. MARK keeps these evidence levels separate so that an attractive recommendation does not become an unsupported delivery promise.

Postal identity: does this PIN fit the address?

Enter the recipient's six-digit destination PIN in the homepage checker. Read the district, state and named postal areas returned. If a locality name differs from the address, confirm it with the recipient rather than silently changing the PIN. One PIN may cover multiple named postal areas; the first listed locality is not necessarily the recipient's exact locality.

If you do not know the PIN, use the local PIN finder with the state and city or district. Pick the relevant named area and compare it with the full address. A search by city alone is not a complete address validation.

Courier evidence: what has actually been confirmed?

Look for the evidence label and its source. A courier-specific positive result for the requested PIN or route is stronger than evidence that the courier operates in the broader city. If the checker reports unavailable evidence, that means it could not establish coverage from that source. It does not necessarily mean the courier refuses delivery.

For a negative result, check whether it applies to your exact route, service or locality. If you still intend to ship, verify with the courier's official booking channel before paying. Do not convert an uncertain result into a yes or no based on a nearby branch alone.

Origin and destination can both matter

A route check can require the dispatch PIN as well as the delivery PIN. MARK's DTDC origin field is optional for comparing available evidence, but needed when the official route verification requires both endpoints. Enter the actual dispatch PIN. Using a different origin can answer a different route question.

Nearby office: useful, but a different signal

A mapped office can help you identify a local courier presence or a possible place to make an enquiry. Distance to a directory point is not the delivery vehicle's route distance. It does not establish opening hours, collection availability or service to a particular building. Confirm those details directly before travelling.

Worked example: three different results

Imagine a destination whose postal district matches the recipient's address. Courier A has a positive route result, Courier B has only a nearby-office listing, and Courier C's checker is unavailable. The first result is the strongest available route evidence. The second is a lead for a direct enquiry. The third remains unknown. This example describes how to compare evidence; it is not a claim about any real PIN or courier.

Final dispatch checklist

1. Confirm the complete address, locality and PIN with the recipient.
2. Select the intended courier and check the actual origin-to-destination route where supported.
3. Confirm the chosen shipping product, parcel weight and size, restricted items, price and any remote-area charges with the booking provider.
4. Keep the receipt and AWB, and give the recipient the courier name.
5. For missing or conflicting evidence, ask the courier rather than treating a recommendation as a guarantee.
