Is 4445 safe, and is it spoofed?

A short code cannot be spoofed in the way an ordinary phone number can, because you are the one starting the conversation. The risk runs the other way: fraudsters send texts that claim to be from a service like this one and ask you to reply or tap a link.

If a text or call is trying to rush you, threaten you, or get a password, one-time code or payment out of you, it is a scam whatever number it shows. Read our guide to the UK number ranges scammers use and how to spot a smishing text, and forward anything suspicious free to 7726.

Where this came from

We do not guess short codes. Every entry in this directory was checked against the organisation that runs the code, or against gov.uk or the regulator:

Checked against this source on 13 August 2026. Short codes and their charges do change — if the operator’s page now says something different, believe the operator.

Checking an ordinary number instead

Short codes are not in Ofcom’s numbering data — only full UK numbers are. If it is a normal 01, 02, 03, 07, 08 or 09 number you want to identify, put it into the phone number checker and you will get its type, its area and the provider Ofcom allocated the range to.

I got a text from a short code I do not recognise – what should I do?

Do not tap any link in it and do not reply unless you are certain who the sender is.
