A Reading 0118 number that signals you belong in Silicon Corridor — from Microsoft Park to Green Park

Reading is the UK’s largest town by population and the economic capital of Silicon Corridor. The Thames Valley generates over £50 billion in annual GVA and hosts more than 200,000 registered businesses, from scale-ups in the Innovation Quarter to the European HQs of Microsoft, Oracle and Cisco clustered along Thames Valley Park. An 0118 number is the clearest signal to professional-services and tech buyers that your company operates in the region rather than further south or west.

Whether you run a software studio in the Innovation District, a professional-services firm in Green Park or a logistics operation near Wokingham, an 0118 number ties your branding to Thames Valley without you having to lease a central office. CallFactory delivers the number together with a full cloud phone system, so there is no on-site hardware to install and your existing handsets, mobiles and softphones keep working.

The Elizabeth line (Crossrail) makes Reading a major transport hub, so an 0118 number anchors your business to a location with direct rail links to Heathrow, London, Swindon and beyond. That matters for companies selling across regions but anchored to Thames Valley logistics.

Area code 0118 was introduced in 1995 as part of PhONEday, when Ofcom renumbered England’s geographic codes. Reading’s predecessor was 0734, which had served as the town’s code during the mobile-phone era. The transition to 0118 marked the town’s formal shift into modern trunk-code assignment and coincided with the technology sector’s acceleration in the Thames Valley.

The 0118 area maps onto the Thames Valley telecoms region. That covers Reading, Wokingham and the surrounding commuter belt within Berkshire, which means porting between providers is straightforward — any UK carrier that holds 0118 stock can release a number to CallFactory through the standard gaining-provider-led process.

Area code 0118 covers Reading and the Thames Valley commuter belt. Major centres and business districts inside the area include:

• Reading city centre — retail, hospitality, the Crossrail / Elizabeth line terminus, IQL business parks
• Thames Valley Park — Microsoft UK HQ (2,500 staff), Oracle UK, Hitachi Capital, Verizon Business, life sciences
• Green Park — Vodafone Business, BG Group, ING Direct, professional services
• Wokingham — business parks, professional services, independent trades
• Earley and Woodley — commuter belt, retail, services
• Tilehurst and Calcot — logistics, distribution, retail
• Theale and Pangbourne — town centres, professional services
• Shinfield and Glenfield — University of Reading Whiteknights campus, SciTech Centre
• Caversham — mixed commercial and residential
• Lower Earley and Sonning — commuter towns with local businesses

If your business is registered at any Thames Valley postcode within the 0118 area, you qualify for an 0118 number.

The Thames Valley is broad, so an 0118 number suits a wide mix of sectors. The three profiles we see most often at CallFactory are:

Tech and software scale-ups — Reading and the M4 corridor host the highest concentration of tech HQs outside London, anchored by Microsoft, Oracle and Cisco. An 0118 number on your pitch deck, your LinkedIn profile and your Companies House filing keeps your company credible in the eyes of investors and enterprise customers, while the cloud platform lets a distributed team answer calls anywhere. For a young tech firm competing for venture capital or enterprise clients, the 0118 signals stability and regional commitment at a glance.

Professional services and consultancies — PwC, Deloitte, KPMG and EY all run Thames Valley offices serving enterprise clients. An 0118 number signals that you operate in the finance and professional-services corridor, reducing friction in procurement and KYC checks. When your clients are evaluating which firm to hire, the 0118 reads as “established in the Thames Valley heartland” rather than a one-person home office.

Logistics, distribution and light manufacturing — The M4 corridor is a spine of distribution and supply-chain operations. An 0118 number anchors your business to the region, which matters when supply-chain partners need to reach you during business hours without ringing a mobile. It also strengthens your case when bidding for regional public-sector contracts that favour local providers.

Outside those three profiles an 0118 still pays off. Higher-education institutions, healthcare practices, trades and membership organisations across Thames Valley all see the same local-trust benefit.

Google treats your business phone number as a geographic signal, which means an 0118 number on your website, your Google Business Profile and UK business directories tells Google that your company belongs to the Thames Valley. Combined with a consistent NAP (Name, Address, Phone) profile across listings, that strengthens your ranking for searches such as “accountant Reading”, “software agency Thames Valley” or “commercial plumber Wokingham”, and improves visibility on Google Maps.

Write the 0118 number in the same format everywhere — same spacing, same separators — because Google only links citations together when they match. CallFactory uses the Ofcom-recommended format 0118 XXXX XXXX, so you can copy it into every listing without introducing variations. Building citations in local directories like Yell, Thomson Local, and industry-specific B2B portals amplifies the local SEO signal, so that customers searching for services in your sector find you first within the Thames Valley region.

Thames Valley-based online retailers and professional-services firms frequently report a lift in phone enquiries once they display an 0118 number on the website. An 0118 reads as local and professional, so customers hesitate less before dialling, which is especially valuable for higher-value sales where a quick conversation closes the deal or prevents a support escalation.

For consultancies — technology, finance, HR, management consulting — the 0118 works as a trust marker on LinkedIn posts, email signatures and Google Ads. You can split inbound calls between the 0118 and any other numbers you run, which lets you attribute leads to the marketing channel that generated the call.

If you already hold an 0118 number with another UK provider, we can port it across at no cost. You keep the existing number and gain the CallFactory feature set — call queues, recording, analytics, IVR — on top of it. Porting itself takes up to five working days and we schedule the cut-over for a date that works for you, which keeps your line live until the moment the number transfers.

If you would rather pick a fresh, unused 0118 number — perhaps one with a memorable digit pattern — the number picker at the top of this page shows live availability. We hold stock across the 0118 range so you can choose whichever reads best for your brand.

Many Thames Valley businesses run an 0118 alongside another number. Common combinations include:

• 0118 + 07 — the 0118 on the website and in advertising, a 07 mobile for existing clients who want direct contact. Forwarding from the 0118 to a mobile is included by default.
• 0118 + 0333 — the 0118 for local customers and a national 0333 number for UK-wide enquiries at standard geographic rates. Both lines land in the same call flow.
• 0118 + 0800 — the 0118 for general reachability and a 0800 freephone number for sales hotlines or campaigns, so callers dial at no cost while you cover the inbound minutes.

All combinations run on a single CallFactory account, so each number is listed on Google Maps with the same address. That strengthens your local discoverability across multiple phone-number types, which matters when customers are comparing options. Current rates for additional numbers are listed on the pricing page.

A Reading 0118 number contains 11 digits in total: the area code 0118 followed by a 7-digit subscriber number.

Standard format: 0118 XXXX XXXX

Use the same format everywhere — your website, Google Business Profile, invoices and directories — because identical formatting is what allows search engines to tie your listings together.

The 0118 number is part of your CallFactory business plan. There are no connection fees and no setup charges. The plan price depends on which features you activate — IVR, call queues, voicebots, call recording — and whether you pay monthly or annually, since the annual plan is cheaper per month. If you need several 0118 numbers, for example one per branch or team, we add them to the same account.

All monthly contracts come with a one-month notice period. Every feature, plan and rate is listed on the pricing page.
