Area code 01273 is the code that Sussex callers associate with Brighton and Hove, but its footprint is much wider than the city. It reaches east to Lewes and the Newhaven ferry port, west along the coast to Shoreham-by-Sea, and north over the South Downs to villages such as Hassocks and Henfield, while several towns that look as though they belong on it sit on a different code. For a business that wants Brighton customers to pick up the phone, it pays to know exactly where the code applies, because a 01273 number on a website or an advert tells callers that the line is part of their local area.

This article maps the 01273 coverage in detail, explains which neighbouring towns use another code, and shows how any business, inside or outside Sussex, can add a 01273 number for Brighton customers and receive their calls wherever the team works. A CallFactory 01273 number is registered on your own business address, which can be anywhere in the UK or abroad.

Which towns does the 01273 area code cover?

The 01273 area is built around the Brighton exchanges and spreads across two counties, East Sussex and West Sussex. The main places on the code:

  • Brighton city centre and Kemptown — the commercial core around the North Laine, Churchill Square and the seafront, plus the Kemptown district to the east, with the densest concentration of business lines on the code
  • Hove and Portslade — the western half of the city, with the Hove exchange carrying a large share of the area’s numbers and Portslade running out to the harbour edge
  • Withdean, Patcham and Hollingbury — the northern suburbs along the London Road and A23 corridor, including the Hollingbury industrial estate
  • Moulsecoomb, Coldean and Falmer — the north-eastern side of the city along the Lewes Road, home to the University of Brighton and the University of Sussex campus
  • Rottingdean — the coastal village east of the city, inside the Brighton and Hove boundary and on the same code
  • Shoreham-by-Sea and Southwick — the West Sussex coast between Portslade and the River Adur, including the commercial and industrial sites around Shoreham Port
  • Lewes — the county town of East Sussex, with council, court and professional-services employers on the 01273 code rather than a code of its own
  • Newhaven and Peacehaven — the coast east of Brighton, with Newhaven’s ferry port to Dieppe and the cliff-top town of Peacehaven
  • Ringmer, Glynde, Barcombe and Plumpton — the villages around Lewes, served by small exchanges that still sit inside the 01273 area
  • Hassocks and Hurstpierpoint — the Mid Sussex villages north of the Downs, on 01273 even though their larger neighbour Burgess Hill is not
  • Henfield and Poynings — the rural fringe to the north-west, showing that the code extends well past the built-up area

A business based anywhere in this footprint will naturally use 01273, but the code is not reserved for local firms. Because a CallFactory number registers on your own business address, a company headquartered elsewhere can publish a 01273 line for its Brighton customers in exactly the same way.

Why the 01273 code still matters to callers

UK area codes were designed so that the opening digits of a number tell the caller roughly where the line sits. Ofcom’s National Telephone Numbering Plan still allocates each geographic code to a named numbering area, which is why a 01273 reads as Brighton in the same way that 0117 reads as Bristol or 0161 as Manchester. Customers notice that signal, and many are more willing to call a number they recognise as local than one that looks distant or anonymous.

For a business, that recognition is the commercial value of the code. A 01273 number on a regional landing page, a local Google Business Profile, a quote or an email signature tells Brighton prospects that you serve their area, and they can call you at standard geographic rates without dialling a distant code. Calls then ring through to your team wherever it sits, whether that is a Brighton office, a head office in another city or staff working across the South East.

The code is about the caller’s perception, not about where your company is registered. CallFactory registers the number on your own business address, so you can choose 01273 because your customers are in Brighton rather than because your office is.

Boundary cases around Brighton

Sussex has a tight cluster of codes, so several towns that sit close to Brighton use a different one. The main cases:

  • Lancing — west, area code 01903. Lancing borders Shoreham-by-Sea along the coast road, yet it belongs to the Worthing numbering area rather than Brighton’s
  • Worthing — west, area code 01903. The largest town on the West Sussex coast anchors its own code, which also covers Littlehampton and Arundel
  • Steyning — north-west, area code 01903. The Adur valley town is closer to Shoreham than to Worthing, but it shares Worthing’s code
  • Burgess Hill — north, area code 01444. Neighbouring Hassocks is on 01273, which makes the boundary here a matter of a couple of miles
  • Haywards Heath — north, area code 01444, sharing the Mid Sussex code with Burgess Hill
  • Seaford — east, area code 01323. Seaford is the next town along the coast from Newhaven, yet it sits on the Eastbourne code
  • Eastbourne — east, area code 01323, which also covers Hailsham and Polegate

These boundaries matter when you choose which number to publish. A business with customers in Worthing or Burgess Hill may prefer that town’s own code, while a company targeting the whole Brighton conurbation, including Lewes and Shoreham, is covered by a single 01273 line. Several local numbers can run on one CallFactory account, so a Brighton line and a Worthing line can reach the same team without callers noticing any difference.

How the 01273 area grew historically

Brighton has a long telephone history. Local press records that it was the first town to get a trunk line to London, in the 1880s, and the town began building one of the country’s first municipal exchanges in 1903. The national STD code for the area was 0273, and in the 1970s the old five-digit local numbers were lengthened to the six digits that 01273 numbers still use today.

PhONEday, on 16 April 1995, inserted a “1” after the leading zero of most UK codes, which turned 0273 into 01273 while leaving local numbers unchanged. Unlike Bristol or Reading, Brighton never needed a new code or longer local numbers, so the six-digit format has survived for half a century.

The most recent change came on 1 October 2014. From that date callers inside the area have had to dial the full 01273 code even for local calls, because Ofcom wanted to release numbers whose first digit after the code is 0 or 1. Those numbers could not previously be used, since a network might confuse them with other codes or special services. The change made almost 200,000 more 01273 numbers available without changing any existing number, and local call prices were not affected. For businesses the practical lesson is simple: always print the number in full as 01273 xxx xxx, which is how every caller now has to dial it.

How to set up a 01273 number for your business

Getting a 01273 line running takes a few minutes of decisions and no local paperwork:

  1. Choose the number. Pick a 01273 number from CallFactory’s stock, including memorable digit patterns, or port an existing 01273 line from your current provider free of charge so that customers keep dialling the number they already know.
  2. Decide where calls go. Set the destination for incoming calls, such as a mobile, a desk phone, the CallFactory app or a hunt group, so that Brighton callers reach the right person wherever your team works. Opening hours, a welcome message and a queue can be added at the same stage.
  3. Go live. CallFactory registers the number on your own business address, which can be anywhere in the UK or abroad, and activates it within one working day. Publish it everywhere in the same format, because Google treats a consistent local number on your website and business listings as a location signal.

A few situations come up often. A Brighton firm moving from Hove to Lewes keeps its 01273 number, because both towns are on the code. A London company opening a Sussex sales desk can publish a 01273 line before it has any office in the area. A multi-site business can give each region its own local number and route them all through one call flow, so a single team handles the whole estate.

Other numbers worth considering alongside 01273

A 01273 number is the strongest choice when your customers are in and around Brighton, but other ranges fit other goals:

  • A neighbouring local code — 01903 for Worthing, Lancing and Steyning, 01444 for Burgess Hill and Haywards Heath, and 01323 for Seaford and Eastbourne. Useful where your customers are concentrated in one of those towns rather than in Brighton itself
  • A national 0333 number — a 0333 number charged at standard geographic rates wherever the caller dials from, which suits businesses with a UK-wide customer base and one published line
  • A freephone 0800 line — an 0800 freephone number where the caller pays nothing, which is the classic fit for sales hotlines and customer-service campaigns
  • A national overview — the UK phone-numbers overview sets out every range Ofcom administers, with guidance on which one suits each commercial profile
  • A combination — a 01273 line for Sussex customers next to a 0333 for the rest of the country, both on one account, so regional and national enquiries land with the same team

The right mix depends on where your callers are. A local code reads as part of the community, a 0333 reads as nationally established, and an 0800 puts the caller’s cost first. Monthly prices and included features for each option are on the pricing page.

Get started

If you want Brighton and Sussex customers to call a number they recognise as local, apply through the Brighton 01273 number page. CallFactory activates the line within one working day, complete with call forwarding to a mobile or landline, a text-to-speech welcome message in any language and call recording for training and quality checks.

Your business does not need a Brighton office for this, because the number is registered on your own business address wherever that is. If your customers are spread across the country as well, a 0333 number can run next to the 01273 line on the same account.
