Frequently Asked Questions
The country code for Jamaica is +1. This code, used for international calls, is part of the North American Numbering Plan (NANP) and is combined with a 10-digit local number for complete international representation (E.164 format).
Jamaican phone numbers follow a 10-digit format, including a 3-digit area code (876 or 658) and a 7-digit local number. For international calls, use the +1 country code followed by the area code and local number (e.g., +1 876 XXX-XXXX). For local calls within Jamaica, the national prefix 1 can be used (e.g., 1 876 XXX-XXXX).
Jamaica uses +1 as it's part of the North American Numbering Plan (NANP), which includes countries and territories in North America, the Caribbean, and parts of the Atlantic and Pacific Oceans. The +1 country code simplifies calling between these regions.
Kingston, Jamaica uses both the 876 and 658 area codes. It's crucial to avoid hardcoding only 876 when dealing with Jamaican phone numbers, as both codes are in active use. Due to number portability, the area code does not always determine the carrier.
Use a regular expression like ^\+1(876|658)[2-9]\d{6}$
for validating E.164 format (recommended). For more flexible local format validation, a regex like /^(?:1)?(?:\s\(?(?:876|658)\)?)?\s[2-9]\d{2}[- ]?\d{4}$/ can be used but remember to normalize to E.164 before storage.
Always use E.164 format (+1876XXXXXXX or +1658XXXXXXX) for storing Jamaican phone numbers in databases and for API communication. This ensures consistency, portability, and compatibility with international standards. You can accept various input formats from users but normalize them to E.164 before storing them.
No, due to number portability in Jamaica, you cannot reliably determine a phone number's carrier from its prefix. Users can switch providers while keeping their original numbers. Always validate the full number format and do not rely on prefixes for carrier identification.
To handle number portability, avoid making assumptions about the carrier based on the number's prefix. Validate numbers using a flexible approach that accommodates both area codes (876 and 658). Ensure your database and APIs can handle number changes due to portability.
The national prefix for making calls within Jamaica is '1'. It is used before the area code and the 7-digit local number, like this: 1 876 XXX-XXXX or 1 658 XXX-XXXX.
Number portability means users can switch carriers and keep their numbers. For storage, always use the E.164 format, which includes the country code (+1) and the full 10-digit number, regardless of the carrier. This ensures consistent and accurate record-keeping.
The Office of Utilities Regulation (OUR) governs Jamaica's telecommunications sector. Consult their website (http://www.our.org.jm) for the most current regulations and information on number portability, area codes, and other relevant topics.
Jamaica Phone Numbers: Format, Area Code & Validation Guide
Jamaica phone numbers follow the North American Numbering Plan (NANP) with two area codes: 876 and 658. This comprehensive guide covers Jamaica phone number validation, E.164 formatting, +1-876 and +1-658 area code handling, and compliance with Office of Utilities Regulation (OUR) requirements for developers building telecommunications applications.
Quick Reference
Jamaica Phone Number Format Specifications
Jamaica uses the North American Numbering Plan (NANP) with a 10-digit format for all local numbers. This structure, combined with the country code, forms the E.164 international format.
Area code 658 is an overlay of 876, meaning the same seven-digit number can exist under both area codes (e.g., +1-876-555-0123 and +1-658-555-0123 are different numbers). Always use the complete 10-digit format to ensure calls route correctly.
Area code 876 was created on May 1, 1997, when Jamaica split from the Caribbean-wide area code 809. The 658 overlay was added on April 30, 2019, to address number exhaustion, with actual number assignments beginning in May 2023.
Understanding NANP Structure
The North American Numbering Plan (NANP) uses the NXX-XXXX format for the seven-digit local number, where:
This format applies to both the area code and the central office code (exchange). The restriction on the first digit prevents conflicts with operator services (0) and long-distance prefixes (1).
Reject these invalid patterns:
Example: A valid Jamaica number
+1-876-606-0123
breaks down as:+1
876
(N=8, X=7, X=6 – valid since first digit is 2–9)606
(N=6, X=0, X=6 – valid since first digit is 2–9)0123
(all digits 0–9 allowed)Core Structure
Detailed Format Table
+1 8XX NXX-XXXX
+1 900 NXX-XXXX
Note on Mobile vs. Landline: Unlike some countries, Jamaica does not use specific number ranges or prefixes to distinguish mobile numbers from landline numbers. Both use the same NXX-XXXX format within the 876 and 658 area codes. Number portability (introduced May 2015) further means that even historical patterns cannot reliably identify the line type. Applications requiring line type identification should use a phone number lookup API or carrier database query.
How to Validate Jamaica Phone Numbers
Use these practical examples to handle Jamaican phone numbers in your applications.
1. Phone Number Validation Rules with Regular Expressions
Validate phone numbers with regular expressions to enforce correct formatting and prevent invalid entries.
Store numbers in E.164 format for consistency and portability. Accept various input formats from users, but normalize them to E.164 before storage.
Edge Cases to Handle:
2. Phone Number Formatting and Normalization to E.164
3. Handling Number Portability Between Carriers
Jamaica has implemented number portability, allowing users to switch carriers while retaining their numbers. Do not assume a carrier based on number prefixes – these can change. Always validate the number format, but expect numbers to be ported across carriers.

Frequently Asked Questions
What is Jamaica's country code for international calls?
Jamaica's country code is +1, shared with other North American Numbering Plan (NANP) countries. To call Jamaica from abroad, dial +1 followed by the area code (876 or 658) and the seven-digit local number.
How many area codes does Jamaica have?
Jamaica has two area codes: 876 (introduced May 1, 1997) and 658 (introduced April 30, 2019). Area code 658 is an overlay, meaning both codes serve the same geographic area.
Do I need to dial 10 digits for local calls in Jamaica?
Yes. Since March 31, 2019, all calls within Jamaica require 10-digit dialing (area code + seven-digit number). This became mandatory when the 658 overlay was implemented.
Can I keep my phone number if I switch carriers in Jamaica?
Yes. Number portability has been available in Jamaica since May 2015, allowing you to switch between FLOW and Digicel while retaining your existing phone number. The process typically takes 1–5 business days.
What format should I use to store Jamaica phone numbers in a database?
Use E.164 format (+18765550123 or +16585550123) for storage. This international standard ensures consistency, portability, and compatibility with telecommunication systems worldwide.
How can I distinguish between mobile and landline numbers in Jamaica?
Jamaica does not use specific number ranges to distinguish mobile from landline numbers – both use the same NXX-XXXX format. Due to number portability, historical patterns are also unreliable. Use a phone number lookup API for real-time line type identification.
What are Jamaica's emergency numbers?
Jamaica's primary emergency numbers are 119 (Police direct access) and 110 (Fire/Police/Ambulance via operator). Alternative numbers 112 and 911 are also supported, primarily for mobile phones and international travelers, routing to emergency services per ITU-T Recommendation E.161.1.
How do I handle SMS delivery to Jamaica numbers?
Use E.164 format for API calls to SMS gateways. Be aware of character limits (160 for standard SMS, 70 for Unicode), obtain explicit opt-in consent per Jamaica's Data Protection Act, and implement delivery receipt tracking. Both major carriers (FLOW and Digicel) support standard SMPP and HTTP SMS APIs.
What validation should I perform for toll-free and premium numbers?
Toll-free numbers use the format
+1-8XX-XXX-XXXX
(where XX = 00, 33, 44, 55, 66, 77, or 88) and premium numbers use+1-900-XXX-XXXX
. Validate these separately from geographic numbers, as they follow different routing and billing rules. Always include the country code +1 when storing these numbers.This guide provides a robust and practical resource for developers working with Jamaican phone numbers.
