Vanity numbers and consecutive number blocks: when they’re worth it

Most businesses take whatever number comes up in search. For some, the number itself is worth choosing: a memorable pattern for advertising, or a consecutive block for a large phone system.

Vanity and memorable numbers

A vanity number spells a word on the keypad, like 1-800-FLOWERS, or follows an easy pattern such as 020 3000 3000.

Worth it when:

  • the number appears in radio, TV or outdoor advertising
  • customers need to remember it without writing it down
  • it reinforces your brand name

Things to know:

  • Word-based vanity numbers are mostly a North American toll-free habit. In Europe, memorable digit patterns work better.
  • The best patterns on older prefixes (800 in the US, 0800 in the UK) are scarce. Newer prefixes such as 833 and 844 have more availability.
  • Premium patterns may carry a higher one-off or monthly price.

Use the “starts with” field in our search to look for patterns, or ask sales to check a specific combination.

Consecutive number blocks

A block is a run of consecutive numbers, for example +44 20 7946 0100 to 0199.

Worth it when:

  • you’re giving every employee a direct-dial number
  • your PBX maps extensions to the last digits (extension 142 = number ending 0142)
  • you want a clean range for a contact centre or branch office

Things to know:

  • Blocks usually come in 10, 100 or 1,000 numbers, depending on the country and range.
  • Some countries allocate numbers to operators in blocks, so consecutive ranges are easier to find there.
  • Blocks are priced per number, often with volume discounts.

Porting existing ranges

If you already have a block with another provider, you can usually port it as a whole range rather than number by number.

Frequently asked questions

Can I choose the exact number I want?

If it’s available, yes. Search by starting digits, or ask sales to check a specific number or pattern.

Are consecutive blocks available in every country?

Not everywhere. Availability depends on the country’s numbering rules and current stock.
