Tango Networks UK Ltd in Nottingham

About Tango Networks UK Ltd’s Nottingham allocation

When Tango Networks UK Ltd is the range holder for +44 115 it means Ofcom recorded Tango Networks UK Ltd as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 2 Nottingham-facing blocks sit against Tango Networks UK Ltd in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Nottingham’s East Midlands telecoms estate is shaped by Nottingham's catchment of roughly 337,000 residents: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Tango Networks UK Ltd’s blocks alongside other range holders on the same 0115 code. Local switching capacity, historic Openreach exchange footprints, and Tango Networks UK Ltd’s wholesale routing arrangements all influence which blocks land in Nottingham rather than elsewhere on the national plan.

Treat this allocation as a starting point, not a verdict on any specific caller. UK numbers are portable, so the current carrier on a given 0115 digit string may differ from the range holder shown — read Range Holder vs current provider for the distinction, and How Ofcom allocates UK phone numbers for the wider context behind the table below.
