Phone number requirements in Singapore
Last updated: 2026-11-12
Singapore regulations require phone numbers to be registered to a verified end user. Before we can activate a Singapore number on your account, we need to confirm who will use it and, for most number types, where they are based. The exact requirements depend on the type of number you order.
This page explains the number types available in Singapore and what you need to provide for each. To place an order, see Order a new business number.
Number types available in Singapore

Local numbers
Local numbers are standard Singapore business lines. They can be registered to a business or an individual.
If you're ordering as a business
- First and last name of an authorised representative
- Company name
- Contact phone number and email address
- A copy of the authorised representative's passport or ID card
- Company registration number (UEN)
- Company registration certificate (e.g. your ACRA business profile)
If you're ordering as an individual
- First and last name
- Contact phone number and email address
- A copy of your passport or ID card
Address (both)
- A street address in Singapore. Include street, block or building number, unit number, postal code and country.
- Proof of address dated within the last 3 months
Usage
- A short description of how the number will be used (see Service usage description)
National numbers
National numbers start with 3 and are designed for cloud and VoIP services. They can be registered to a business or an individual.
If you're ordering as a business
- First and last name of an authorised representative
- Company name
- Contact phone number
- A copy of the authorised representative's passport or ID card
- Company registration certificate (e.g. your ACRA business profile)
If you're ordering as an individual
- First and last name
- Contact phone number
- A copy of your passport or ID card
Address (both)
- A street address in Singapore (street, block or building number, unit number, postal code and country)
- Proof of address dated within the last 3 months
Toll-free numbers
Toll-free 1800 numbers are free for callers to dial within Singapore. They have the lightest requirements of any Singapore number type, and you don't need an address in Singapore.
If you're ordering as a business
- First and last name of an authorised representative
- Company name
- Contact phone number
If you're ordering as an individual
- First and last name
- Contact phone number
Address (both)
- A street address anywhere in the world (street, building number, postal code, city and country). No proof of address is needed.
Service usage description
Local number orders need a short description of how you plan to use the number. One or two sentences is enough. For example:
- "Main inbound line for our Singapore office, answered by reception."
- "Sales line for customers in Singapore, routed to our sales team."
Rules that apply to every Singapore number
- Proof of address must be recent. Where proof of address is required, it must show the same name and address you enter on the order and be dated within the last 3 months. Utility bills, bank statements, tenancy agreements or official letters are typical examples.
- Use the exact legal name. For business orders, enter your company name exactly as it appears in your ACRA registration. Trading names or abbreviations will delay the order.
- Activation time. Once we've received all your documents, it takes about 72 hours to validate them and activate the number.
ID documents
All documents are reviewed before a number is activated. We may ask for additional documentation, and we can decline any document we're unable to verify or that doesn't meet Singapore regulatory requirements.
Ordering more numbers later
Once your details have been verified, you don't need to start from scratch for every order. We keep your approved company and address information on file, so additional numbers of the same type can usually be activated faster. If your company details or address change, let us know so we can update your registration.
Common reasons orders are delayed
- No Singapore address for a local or national number. Use a Singapore street address, or choose a toll-free number instead.
- Proof of address is older than 3 months. Upload a more recent document.
- Name mismatch. The name on the registration certificate, ID and proof of address must match the order.
- Missing UEN or usage description on a local number order. Both are required.
