Regular expressions (regex) are important for validating structured data like Social Security Numbers (SSNs). In applications that require user identification or verification, such as financial services or human resources platforms, ensuring the correct format of SSNs is significant. A common regex pattern for SSN validation is ^\\d{3}-\\d{2}-\\d{4}$, which matches the standard format of SSNs in the United States.

What is SSN Regex?

An SSN in the United States typically follows a "AAA-GG-SSSS" format, where A, G, and S are digits. The regex for SSN validation should match this structure.

The SSN Regex Pattern

The regex pattern for a standard U.S. SSN is:

  • ^\\d{3}-\\d{2}-\\d{4}$

  • This pattern ensures that the SSN consists of three digits, followed by a hyphen, two digits, another hyphen, and four digits.

How to Validate SSN Using Regex in Go?

Validating an SSN in Go using regex involves the following steps:

  1. Define the regex pattern for a valid SSN.

  2. Use the regexp package in Go to compile the regex pattern.

  3. Validate the SSN strings with the compiled regex.

package main
import (
func isValidSSN(ssn string) bool {
    // Define the regex pattern
    var ssnRegex = regexp.MustCompile(`^\d{3}-\d{2}-\d{4}$`)
    return ssnRegex.MatchString(ssn)
func main() {
    testSSN := "123-45-6789"
    fmt.Printf("Is '%s' a valid SSN? %t\n", testSSN, isValidSSN(testSSN))

Uses of SSN Regex Validation

SSN regex validation is particularly important in:

  1. User Verification Processes: Validating SSNs is crucial in applications that require identity verification, such as in banking or employment.

  2. Data Accuracy in Record Keeping: Ensuring accurate and standardized SSN entries in databases.

  3. Compliance and Security: Adhering to legal and security standards that require the correct handling and validation of SSNs.

What next?

For developers, particularly in sectors like finance and human resources where SSNs are frequently used, the ability to accurately validate these numbers is essential. Tools like Akto's SSN Validator can help in testing of SSN validation logic.
