I know today it's Easter. Happy Easter to everyone. If you Registration a limited company, you will see RC: 1234567
It shows the company it's a registered limited company. The tax identification number comes with the certificate of a registered limited company. BN means business name. Business names don't end with anything, eg Bujee Child Clothes or they can end with Enterprise or services or concept. I saw where someone was trying to register a limited company in the business name section, it is a no no. Once a name does not end with LTD, it automatically a business name and must be registered within the business name section.
Business name certificates, don't come with tax identification number on their certificate. You can apply through the nearest Federal Inland Revenue Office close to where the business is situated, or verify with your BN number on tin verification website, you can search on Google.
Then for IT, IT appears on incorporated trustee certificate. If you Registered a foundation, church, mosque, club, society and association you will see IT: 2345678
Yes all IT must obtain scmul certificate.
Learn something new and enjoy your Easter holiday.
