Accountable now supports GLN numbers for Peppol routing, which means you can successfully send invoices to clients that require this identifier.

This article explains what a GLN number is, when you need it, and how to use it in Accountable.

What is a GLN number?

A GLN (Global Location Number) is a unique 13-digit identifier used to identify organisations or specific locations within organisations.

It is part of the GS1 identification system and is widely used in supply chains, healthcare, logistics, and public administration.

Within the Peppol network, a GLN can be used to route invoices to the correct organisation or department.

Example of a GLN:

Unlike VAT numbers, GLNs do not indicate tax registration. Their purpose is only to identify a specific business location or entity.

When do you need to use a GLN?

You only need to use a GLN if your client explicitly provides one for Peppol invoicing.

This is common for organisations such as:

• public institutions

• hospitals and healthcare providers

• large corporations

• international organisations

These organisations sometimes require invoices to be sent to a specific department or purchasing system, which is why they use GLN identifiers instead of VAT numbers.

If your client does not provide a GLN, you should continue using their VAT number as usual.

GLN vs VAT number for Peppol

In most cases, VAT numbers remain the standard identifier for Peppol invoicing.

GLN identifiers are only needed for specific organisations that require them.

How to send a Peppol invoice using a GLN in Accountable

If your client provided a GLN, you can add it to their client profile.

1. Add the GLN to your client

1. Open the client profile in Accountable

2. Locate the GLN field

3. Enter the 13-digit GLN number provided by your client

Important:

• Only enter the number itself

• Do not add the Peppol prefix :

• The GLN field is available only for business clients

2. Send the invoice via Peppol

Once the GLN is saved:

1. Create your invoice as usual

2. Choose Send via Peppol

3. Accountable will automatically use the GLN for routing if it is present

Do you always need a GLN?

No.

Most organisations receive Peppol invoices using their VAT number, and this will continue to work as before.

You only need a GLN when your client specifically asks you to use one for Peppol invoicing.

✅ Summary

• A GLN is a 13-digit identifier used for Peppol routing

• It is mainly used by public sector, healthcare, and large organisations

• In Accountable, you can add the GLN in the client settings

• Use it only when your client explicitly provides it
