Why Phone Number Change Flows Are High-Risk and High-Volume

📌 Your phone is your key. Whether it's SMS-based multi-factor authentication (MFA), OTPs, or account recovery, most users rely on mobile verification.

📈 In banking and fintech, support teams see phone updates as a top 5 ticket driver, especially during SIM upgrades, travel, or lost-device scenarios.

🔒 Phone number change flows must balance:

• Security (preventing impersonation/fraud)

• Compliance (GDPR, SOC 2, and ISO/IEC 42001)

• UX (users are often stressed and need fast resolution)
