Find Phone Numbers in United Kingdom Directories
Looking for a specific company's contact information? Use trusted local business directories to find phone numbers and addresses.
Checkatrade
Trade-based business directory. You won't find hotels or travel agents here but if you're looking for a plumber or electrician then this site provides it. The website bases its entries on good feedback from previous customers so it doesn't include all trades, just reliable ones.
BT - The Phone Book
British Telecom's Directory Enquiries service, giving phone numbers of people and businesses in the UK. The place, or at least part of postcode, needed for each search. Number of searches per day/month is limited for each user. Includes England, Scotland, Wales, Northern Ireland, Isle of Man and Guernsey. Also in Welsh.
Yell
Comprehensive Yellow Pages directory for businesses in the UK. Includes maps and reviews from users.
Cylex UK
Comprehensive business directory searchable by keyword or category. Includes reviews from users of the services or companies. Also has links to vouchers and companies with special offers. Results show maps, full details including websites and also, quite handily, other similar local businesses or services.
ukphonebook.com
To see any listings (of businesses and people), you have to register (for free). The searches are a little more flexible than the BT site, finds people or business "near" a place so location is less crucial. Now limited to five free searches (credits) a day. Information provided by Simunix who also work on the 118 365 directory assistance number.
Scoot
Business directory for the UK.
UK Small Business Directory
Business directory with over 200,000 listings. Not the most user friendly in terms of finding something in a location right away - you can't type in a type of business and location (for example, hotels in Birmingham). You type in what you're looking for and then have to scroll through all the entries which are arranged in an alphabetical order. There are drop down options for ordering the results if you're searching by town or category but it's clunky and not the easiest to find things. There is also a distinct lack of telephone numbers included on the entries - some companies have them listed but you need to click on the telephone icon below the address to get to it.
TouchLocal
Simple to use business directory site - the phone numbers are clear and visible on the results. Search via keyword or category.
Local Life
Business directory which also provides information about the local area such as things to do and hotels. Simple to use business and services directory with user reviews which are useful when deciding which to choose. It has a 'get a quote' section quite prominently on the front page but if you're just looking for the telephone number of a service or company then use the search boxes at the top of the screen with keywords or the categories further down. You will need to click on the 'call' icon to show the telephone number.

Calling from United Kingdom to the United States
To call United States from United Kingdom, follow this exact dialing sequence:
00 + 1 + Area Code + 7-digit phone number
- 00 - United Kingdom's international access code
- 1 - United States country code
- Area Code - Specific U.S. area code
- 7-digit number - The local phone number
Example: To call (312) 555-0123 from United Kingdom, dial: 00 1 312 555 0123
Useful tip: Before placing your call, confirm the number belongs to the intended recipient with this US phone number verification tool. If you know you should be calling to a specific U.S. city, let's say Chicago, then you should use phone number lookup tool for Chicago, Illinois, or its area codes (312, 773, 872).
