GUID (Globally Unique Identifier) validation is crucial in software applications where unique identifiers are required. A regex pattern for GUID validation typically matches the format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx where x is a hexadecimal digit.

GUID Regex

A standard GUID is a 128-bit number, represented in a specific format.

The GUID Regex Pattern

The regex pattern for a standard GUID is:

  • This pattern ensures that the GUID is in the correct format.

How to Validate GUIDs Using Regex in Go?

Validating a GUID in Go with regex involves:

  1. Define the regex pattern for a valid GUID.

  2. Compile the regex using the regexp package in Go.

  3. Validate the GUID strings with the compiled regex.

package main

import (

func isValidGUID(guid string) bool {
    // Define the regex pattern
    var guidRegex = regexp.MustCompile(`^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-5][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}$`)
    return guidRegex.MatchString(guid)

func main() {
    testGUID := "123e4567-e89b-12d3-a456-426614174000"
    fmt.Printf("Is '%s' a valid GUID? %t\n", testGUID, isValidGUID(testGUID))

Uses of GUID Regex Validation

  • Unique Resource Identification: Ensuring each GUID is unique and correctly formatted in systems like databases and distributed systems.

  • Data Integrity: Validating GUIDs to maintain data consistency across different parts of an application or different applications.

  • API Communication: Ensuring that GUIDs used in API requests and responses are in the correct format.
