Have you received a shipping confirmation from an online store but are unsure which number to use to track your parcel? You are not alone. Many customers in Ireland receive several reference numbers when sending or receiving packages, and identifying the correct one can sometimes be confusing.
An Post shipments may include tracking references, order numbers, postage receipts, and other transaction details. Although these numbers may look similar, they serve different purposes.
Knowing how an An Post tracking number is structured, where to find it, and how to recognize the correct reference can save time and make checking your delivery much easier.
What Does an An Post Tracking Number Look Like?
An Post tracking numbers can follow different formats depending on the service and shipment type.
A commonly used international postal tracking format consists of 13 characters:
- Two letters at the beginning.
- Nine numerical digits in the middle.
- Two letters at the end.
For example:
RR123456789IE
This is an illustrative tracking number showing the general structure of a commonly used international postal reference.
The letters and numbers help identify and distinguish a shipment within the postal tracking system. However, not every An Post shipment necessarily uses this exact format.
Some services and delivery arrangements may use different reference formats.
What Do the Letters and Numbers Mean?
Understanding the general structure of a postal tracking reference can help you recognize whether you have the correct number.
1. First Two Letters
The first two characters are letters that form part of the postal service indicator.
They are associated with the type of postal service or shipment category. Their exact meaning depends on the applicable postal numbering system.
2. Nine Numerical Digits
The middle section contains nine digits in the common international postal format.
These numbers form the shipment’s numerical reference. The final digit is used as a check digit in the international S10 postal numbering structure.
3. Last Two Letters
The final two characters generally represent the country code associated with the issuing postal authority.
For example, IE is the country code for Ireland.
It is important to remember that a tracking number’s format alone does not confirm that a parcel has been dispatched or accepted by An Post. The shipment must also have corresponding tracking information.
Where Can You Find Your An Post Tracking Number?
If you are expecting a parcel but cannot locate its tracking reference, check the following places.
Online shopping confirmation: Retailers often provide shipping information through an order dispatch email. Look for a section labelled Tracking Number, Shipment Details, or Delivery Information.
SMS notifications: Some retailers and delivery services send tracking references through text messages.
Post office receipt: If you sent a parcel at an An Post branch, check the receipt provided after completing the transaction.
Sender’s confirmation: If someone else sent the package, ask them to share the tracking reference.
Online shopping account: Sign in to the website where you placed your order and open the relevant order details. Shipping information may be available there.
Always copy the complete reference carefully, including its letters and numbers.
Is an An Post Tracking Number the Same as a Trans Ref ID?
No. These two references serve different purposes.
A tracking number identifies a shipment and allows customers to check available delivery updates.
A Trans Ref ID, on the other hand, is a transaction reference associated with a postal payment or receipt. It is not necessarily the number used to follow a parcel through the delivery network.
For example, if you purchase postage at a post office, your receipt may contain several pieces of information. You should look specifically for the shipment tracking reference rather than assuming that every printed number is suitable for tracking.
If you enter a payment reference instead of the actual tracking number, the tracking system may not recognize it.
How to Check Your An Post Tracking Number Online
Once you have identified the correct shipment reference, checking your parcel is straightforward.
- Locate your reference: Find the tracking number in your dispatch email, receipt, or shipping notification.
- Open a tracking resource: Visit AnPost Tracking to access the parcel tracking Website.
- Enter your number: Carefully type or paste the complete tracking reference.
- Submit your search: Continue to the official tracking service to retrieve available shipment information.
- Review the results: Check the latest recorded shipment event and delivery information.
This process helps customers in Ireland access parcel tracking information without confusing their shipment reference with an order or payment number.
Why Is My An Post Tracking Number Not Recognized?
Sometimes, a tracking number may not return any results when you enter it online.
There are several possible reasons.
Incorrect characters: A single missing letter or digit can prevent the system from identifying the shipment.
Newly generated reference: The sender may have created a shipping label before physically handing over the package.
Not yet scanned: The shipment may need to be accepted and processed before tracking information becomes available.
Wrong reference type: You may be entering an order number, payment reference, or another transaction ID instead of the shipment tracking number.
Different shipping service: Not every postal or delivery service uses the same tracking format.
If your number is not recognized, verify it with the sender and try again after allowing time for the first tracking update.
Can Every An Post Parcel Be Tracked?
No. Tracking availability depends on the postal product or service selected.
Some shipments include tracking information, while others may provide limited or no online tracking.
If you are sending an important package, check the available service features before purchasing postage. If you are receiving an online order, ask the seller whether the selected shipping method includes tracking.
This is especially important for international deliveries, where tracking coverage and update frequency can vary between postal networks.
