Postal Authority
Royal Mail Ltd is the postal authority of United Kingdom. With over 500 years of history, they began as exclusive postal service for the King and is court. Today, they deliver mail six days a week to the 32 million homes in the United Kingdom.
Prior to privatization, Post Office Limited was a subsidiary of Royal Mail group with Royal Mail responsible for delivery letters and parcels while the Post Office provided counter services. The Postal Service Act passed in 2011 separated the Royal Mail Group Ltd and the Post Office Ltd, with Royal Mail going private in 2013.

Name Conventions
Population Names
In the United Kingdom, names are predominately English/Latin, in the western naming format:
[opt: title/ prenominal] [given name] [opt: middle given name(s)] [FAMILY NAME][opt: suffix /post nominal]
Examples:
-Mr. John Smith MD
-Sir Ian McKnighted
-John Parliament, MP
The United Kingdom has no official naming law, and names are generally accepted unless they include obscenities, numerals, or symbols. Registry offices may reject names that are clearly offensive or unorthodox. Patrilineal naming is common, but individuals may choose to retain or hyphenate surnames upon marriage.
While English is the dominant language, Welsh names are also prevalent in Wales and may include diacritics. Titles of nobility (e.g., Sir, Dame, Lord, Duke) may appear in formal or hereditary names, though such titles have ceremonial or social significance rather than legal status.
Organizational Names
Company names in the UK must include a recognized legal structure as defined by Companies House. Common suffixes include:
- Ltd (Private Limited Company)
- PLC (Public Limited Company)
- LLP (Limited Liability Partnership)
- UNLTD (Unlimited Company)
- IPS (Industrial and Provident Society)
- RC (Registered Charity)
While Royal Mail does contain over 1.4 million company names, they do not have all the company names in the United Kingdom. Having said that, Royal Mail is one of the few postal authorities that actually does keep and make available a significant number of Organization name and addresses.
