Customer number, activation code and date

Do you need your customer number, activation code and date to register for MyProximus? You can look them up or have them sent to you.

If you only need your customer number, e.g. for our customer service, you can look it up, have it sent to you, or (if you already have a MyProximus account) find it on MyProximus.

Find them on your payment statement, your bill or welcome letter:

Example of a bill or payment statement with client number

On top of your bill or payment statement, you will find your customer number (9 digits).

In the middle, under the mention Your bill online? or Your payment statement online?, you will find your activation code (8 characters – numerals and capital letters) and date.

NB: only use the activation code and date of a document that is not more than 1 month old.

Your welcome letter also mentions these details but be aware that this letter is valid for only 1 month.

Receive them by SMS or by post:

  • If using your Proximus fixed line, call 0800 55 263 (for private customers only).
