09 premium rate range
0900
Who called you from 0900?
Calls from 0900 numbers usually come from organisations rather than individuals: helplines, switchboards, customer service teams and outbound call centres. The allocation data below shows which phone companies hold 0900 numbers.
Was it a scam?
The code alone can't tell you, and anyone who says otherwise is guessing. What settles it is the call itself: a genuine organisation survives you hanging up and ringing back on the number from its website or your paperwork. If the caller wanted money, bank details, one-time codes or remote access to your computer, treat it as hostile.
What to do now
- Missed call, no voicemail? Don't ring back numbers you don't recognise, especially in this range. Anything important comes back properly.
- Suspicious call: forward the number and what was said to 7726, free on every UK network.
- Lost money or gave away details: Action Fraud, 0300 123 2040 (Police Scotland on 101 in Scotland), and your bank on the number on your card.
- If a caller claims to be from a government department, ring the department back on its official number, which ContactNumbers lists with the source.

Which companies hold 0900 numbers
Ofcom allocates numbers to phone companies in blocks. These are the operators holding the most 0900 blocks.
