Stour Marine Limited in Liverpool

About Stour Marine Limited’s Liverpool allocation

When Stour Marine Limited is the range holder for +44 151 it means Ofcom recorded Stour Marine Limited as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 2 Liverpool-facing blocks sit against Stour Marine Limited in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Liverpool’s Merseyside telecoms estate is shaped by Liverpool's catchment of roughly 500,000 residents: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Stour Marine Limited’s blocks alongside other range holders on the same 0151 code. Local switching capacity, historic Openreach exchange footprints, and Stour Marine Limited’s wholesale routing arrangements all influence which blocks land in Liverpool 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 0151 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.
