What is the 787 Area Code? Time Zone and Location
- Area code 787 serves Puerto Rico and has a single overlay (939) that serves the same geographic area.
- Combined with overlay 939, area code 787 covers 81 cities and 74 counties across the entire Commonwealth of Puerto Rico, serving a population of 3,205,918.
- Major municipalities covered include San Juan, Bayamon, Carolina, Ponce, Caguas, Guaynabo, Mayaguez, Arecibo, Aguadilla, Fajardo, and Trujillo Alto.
- Puerto Rico follows the Atlantic Standard Time zone (AST) at UTC-4. Daylight Saving Time is not observed in Puerto Rico, so the island remains on AST year-round.
- Area code 787 was put into service on March 1, 1996, and was the 166th area code in service, created to relieve the pressure on the 809 area code as numbers in 809 were being exhausted across the Caribbean.
- Area code 939 was added as an overlay on September 15, 2001, to provide additional numbering capacity across the same geographic region.
- 10-digit dialing mandatory for all local calls within the 787/939 overlay complex.

| Common Labels | Medicare impersonator, prescription drug spam caller, credit card debt harasser, financial fraud caller |
| Spoofing Risk | Scammers spoof local 787 numbers to appear as familiar Puerto Rico calls, knowing island residents are more likely to answer what appears to be a local call from San Juan, Bayamon, or Caguas |
| Typical Strategy | Neighbor spoofing — faking a familiar Puerto Rico municipality number to build trust before making fraudulent requests, often targeting Spanish-speaking residents with bilingual scam scripts |
| Signature Scam — Medicare & Prescription Drug Fraud | Callers posing as Medicare representatives or prescription drug plan providers target Puerto Rico's older population — claiming new Medicare cards, updated drug benefits, or prescription discounts require verification of Medicare numbers, Social Security numbers, or banking information over the phone |
| Signature Scam — Credit Card Debt Relief | High-pressure calls claim to offer credit card debt settlement, consolidation, or relief programs — asking victims to provide card numbers and personal financial details to "enroll" in services that either don't exist or charge hidden fees |
| Signature Scam — Medicaid Healthcare Fraud | Puerto Rico has experienced significant Medicaid fraud schemes involving fake healthcare providers billing for services never rendered — the HHS Office of Inspector General has conducted multiple reviews of Puerto Rico's Medicaid Fraud Control Unit, specifically due to the island's disproportionate fraud exposure |
| Hurricane Recovery Fraud | Scammers have historically targeted Puerto Rico residents in the aftermath of hurricanes by posing as FEMA representatives, disaster relief organizations, or contractors — requesting upfront payments or personal information to process fake disaster assistance claims |
| Reporting Authority | Report suspicious calls to the FTC at ReportFraud.ftc.gov or call 1-877-382-4357; for Medicare fraud, call 1-800-MEDICARE (1-800-633-4227) |
| Key Risk Indicator | Unsolicited calls about Medicare cards or drug plan changes, credit card debt settlement offers, FEMA or disaster relief impersonators, or any caller requesting payment by gift card or wire transfer |
| Safety Tip | Medicare never calls out of the blue to say you'll lose coverage, and will never ask for your Medicare number to send you a new card or enroll you in a benefit — always hang up and call 1-800-MEDICARE directly to verify any claims about your coverage |
What Are the Business Benefits of the 787 Area Code?
| Local Presence | A 787 number is the definitive signal of local identity across all of Puerto Rico — as one of only two area codes on the island, it is universally recognized by Puerto Rican consumers as a trusted local number |
|---|---|
| Customer Trust Factor | A local 787 number dramatically increases answer rates vs. unknown mainland US or international numbers in a market where local identity and community trust are paramount |
| Bilingual Market Access | Puerto Rico's primary language is Spanish, though English is widely used — a 787 number is essential for businesses engaging the island's bilingual consumer base and serves as a credibility signal to Spanish-speaking customers |
| Coverage Advantage | One number covers all 81 municipalities across the entire island of Puerto Rico — from the San Juan metropolitan area and Bayamon to the western city of Mayaguez, the southern city of Ponce, and the eastern coastal town of Fajardo |
| VoIP Compatibility | Easily available for SaaS platforms, call centers, and remote teams serving the Puerto Rico market |

| Scalability | Covers roughly 7.77 million unique phone numbers across the 787/939 overlay complex, with 17.5% of prefixes still inactive — ensuring strong number availability for the foreseeable future |
| US Territory Advantage | As a US territory, Puerto Rico operates fully within the NANP — meaning a 787 number functions identically to any US area code for mainland callers, with no international calling complications or extra charges |
| Marketing Use | Ideal for local SEO, Spanish-language digital ads, and customer outreach across San Juan, Bayamon, Ponce, Carolina, Caguas, Mayaguez, and surrounding municipalities |
| Diaspora Connectivity | Puerto Rico has a large diaspora across the continental US — particularly in New York, Florida, and New Jersey — and a 787 number helps businesses and families maintain affordable local connections to the island |
| Call Routing Flexibility | Can route calls globally while appearing local to Puerto Rican customers — particularly valuable for pharmaceutical, tourism, and financial services companies managing operations across the island and the mainland |
| Top Industries | Manufacturing (pharmaceuticals, electronics, and medical devices — Puerto Rico produces roughly 25% of US pharmaceuticals), finance and banking, tourism and hospitality (El Yunque National Forest, Old San Juan, beach resorts), agriculture (coffee and rum production), healthcare, and education benefit most from a local 787 presence |
| Use Case Examples | AI receptionist, pharmaceutical and biotech support lines, hotel and resort booking services, healthcare practices (including Medicaid-enrolled providers), financial advisory services, rum and coffee export businesses, government agency lines, and tourism and hospitality operators |
