Postal Code Format
In India, postal codes are called PIN (Postal Index Number) codes and consist of 6 digits. The first digit represents the region, the first two digits represent the sub-region or circle, the third digit represents the sorting district, and the last three digits represent the specific post office. PIN codes appear after the city and state name.

Name Conventions
Population Names
In India, naming conventions vary significantly by region, religion, and cultural background. However, a common structure includes:
[opt: title] [given name] [opt: middle name/father's name] [FAMILY NAME/surname]
Examples:
- Mr. Rajesh Kumar Sharma
- Smt. Priya Patel
- S. P. Balasubrahmanyam *
- Prof. Dr. Amit Singh
- Mrs. Lakshmi Rao
- Reddy Prasad (alternate format)
Many Indian names reflect religious and regional traditions. Hindu names often reference deities or Sanskrit words. Muslim names follow Arabic conventions. Sikh names typically include Singh (male) or Kaur (female) as middle names.
*In South India, patronymic naming is common, where a person's name includes their father's name or village name. For example, "S. Ramesh" where "S" stands for the father's name. On official documents the entire name or initials only, can appear as a surname.
Common titles include Mr., Mrs., Ms., Dr., Prof., and Shri/Sri (respectful term for men), Smt./Srimati (married women), and Kumari (unmarried women).
After marriage, women may adopt their husband's family name, though this varies by region and personal choice. Some women retain their maiden names.
Names may be written in various Indian scripts (Devanagari, Tamil, Bengali, etc.) but are romanized for official documents using the Latin alphabet.
Organizational Names:
Indian businesses must register with the Ministry of Corporate Affairs (MCA) or appropriate state authorities. Common legal entity designations include:
Private Limited (Pvt. Ltd.) – Private limited company
Limited (Ltd.) – Public limited company
LLP – Limited Liability Partnership
OPC – One Person Company
Proprietorship – Sole proprietorship (no suffix required)
Company names must be unique, not identical or similar to existing companies, and cannot include words that suggest government affiliation without approval. Names may be in English, Hindi, or any regional language recognized by the Constitution.
