IMEI Number (Mobile Device) Regex for Go

What this pattern does

This page provides a lightweight, single-purpose regular expression for matching imei number (mobile device), ported and verified for Go. Identity and credential patterns need both correctness and safety, since they're frequent targets for adversarial input. The snippet below is ready to drop into your Go project — whether you're validating in a Gin handler, a gRPC service, or a command-line tool.

Go Implementation

// IMEI Number (Mobile Device)
// ReDoS-safe | RegexVault — Identity & PII > Digital Identity

package validation

import "regexp"

var imeiNumberMobileDeviceRe = regexp.MustCompile(`^[0-9]{15}$`)

func ValidateImeiNumberMobileDevice(s string) bool {
    return imeiNumberMobileDeviceRe.MatchString(s)
}

// Example
// fmt.Println(ValidateImeiNumberMobileDevice("356938035643809")) // true

Test Cases

When to use this pattern

This pattern is drawn from the Identity & PII > Digital Identity category and carries a ReDoS-safe certification. That matters for Go developers because Go's RE2 engine is inherently safe from catastrophic backtracking, but this pattern has been additionally verified for correctness. RegexVault audits patterns against known backtracking attack vectors, ensuring you have the necessary context before using this regex in a high-stakes production environment.

Common Pitfalls

Technical Notes

IMEI structure: 8-digit TAC (Type Allocation Code, identifies manufacturer/model) + 6-digit serial number + 1 Luhn check digit. IMEI2 is used for dual-SIM devices. IMEISV is 16 digits (includes software version). Always validate Luhn checksum.
