What the prefix tells you
- Number type
- Freephone
- Numbering area
- UK-wide
- Format
- 0800 xxx xxxx (some shorter formats also exist)
A free callback tariff does not verify a caller’s identity. For an unexpected request, find the organisation’s published number independently.
How much does it cost to call?
Calls to 0800 and 0808 numbers are free from UK consumer landlines and mobiles. Overseas and roaming arrangements can differ; check before calling from abroad.
These are UK call-cost rules, not a quote for your individual plan. Check your provider’s tariff and any roaming terms before calling.

Allocation records identify number blocks, not private subscribers. Porting and caller ID spoofing mean the prefix cannot prove the current network, caller’s identity or physical location.
