FAQs about Vonage Business Limited on 0191

Why does Vonage Business Limited appear on Tyneside / Newcastle / Sunderland / Durham (0191) numbers?

Vonage Business Limited is listed in Ofcom's UK Numbering Data feed as the originally-allocated range holder for 6 number blocks on the 0191 dialling code, which covers Tyneside / Newcastle / Sunderland / Durham. That allocation pre-dates any individual customer — it simply means Ofcom recognised Vonage Business Limited as the wholesale operator entitled to issue those digits when the block was first allocated.

Are calls from a Tyneside / Newcastle / Sunderland / Durham Vonage Business Limited-allocated number safe?

An Ofcom allocation only tells you which provider the block was issued to; it is not a safety verdict. UK numbers can be ported between networks, and any UK area code can be spoofed by an overseas caller. Paste the specific 0191 number into the lookup above to combine the Vonage Business Limited range data with a live AI internet check for forum reports, scam databases, and business listings.

Has Vonage Business Limited's 0191 block been updated recently?

Yes — the table above is sourced from Ofcom's public UK Numbering Data feed, which we re-ingest every week (typically Wednesday). Any block that has been re-assigned, withdrawn or marked free will appear with its new status on the next refresh. Numbers within an allocated block can still be ported to another carrier in between Ofcom updates; see our range-holder-vs-current-provider guide for the distinction.
