Complete guide to international calling cards. Learn how they work (PIN, access numbers, DTMF), their history from 1976 to $3.3B peak in 2000, hidden fees and FTC scams, and cheaper VoIP alternatives for 2026.

International calling cards are prepaid cards that let you make overseas calls by dialing an access number and entering a PIN. They peaked at $3.3 billion in sales in 2000 but have been largely replaced by VoIP apps that offer cheaper rates (from $0.008/min) without hidden fees, PINs, or expiration dates.

This guide covers how calling cards work, their history from 1976 to 2026, common scams and hidden fees (the FTC found one provider delivered only 45% of advertised minutes), and the modern alternatives that are now cheaper and more convenient.

How International Calling Cards Work

Step 1: Buy a card — physical (scratch-off PIN) or digital (email/text delivery). Typically $5, $10, or $20.

Step 2: Dial the access number — a toll-free or local number connecting to the provider's system.

Step 3: Enter your PIN — 4-12 digits. System reads DTMF tones (dual-frequency beeps) to authenticate.

Step 4: Dial the destination — full international number. Balance deducted per minute.

Technical detail: DTMF was developed by Bell Labs in the 1960s. Each key generates two simultaneous tones — one low-frequency and one high-frequency — using 8 total frequencies.
