Yes, US passports do have letters in them. Specifically, the passport number found in a US passport includes both letters and numbers.
Key Features of Modern US Passports
Modern US passports, particularly the next generation passport book, are designed with advanced security and identification features. These features ensure the document's authenticity and protect the traveler's identity.
Here's how letters are incorporated and other notable characteristics:
- Alphanumeric Passport Number: The unique passport number assigned to each document is an alphanumeric sequence. This means it is composed of both letters and numbers, which contributes to its distinctiveness and aids in the global identification and tracking of the passport.
- Durable Data Page: The next generation passport book features a robust, polycarbonate, multi-layered plastic data page. This material is highly durable and resistant to tampering, enhancing the security and longevity of the passport.
- Embedded Electronic Chip: For enhanced security and digital verification, US passport books also incorporate a small integrated circuit (or “chip”). This chip is typically embedded within the back cover of the passport and stores biometric and biographical data, allowing for quick and secure electronic verification at ports of entry.
These combined features make US passports highly secure and efficient for international travel, with the alphanumeric passport number being a key component of their unique identification system.
