It's no secret that phone numbers are among the key details businesses collect from customers.
Why? From SMS marketing and delivery updates to account verification and fraud prevention, phone numbers power everything. In fact, close to 70% of businesses text customers. However, many fail to confirm if the numbers in their databases are active, correct, and usable.
This can pose a massive issue. The quality of data stored across marketing tools, customer relationship management (CRM) systems, and contact centers starts eroding. This means your campaigns don't perform desirably, communications fail, and operational expenses spike. You become more susceptible to fraud too.
Phone validation can effectively deal with these challenges, though, especially when paired with other practices focused on data quality. Let's explore its meaning and importance, common challenges, and how to ensure efficient implementation.
Understanding Phone Validation
It's the process that lets you check if a phone number is authentic, formatted correctly, and can receive messages and calls. Typically, with modern validation tools, you can:
- Confirm the validity of a number and if calls can be placed to it
- Standardize phone numbers based on international formats
- Figure out if the number is a landline, toll-free, mobile, or VoIP
- Detect the dialing and country code as well as carrier
- Spot numbers that are disconnected, inactive, or invalid
Phone validation solutions don't just check the number of digits. Rather, they compare phone data against reliable reference and telecommunication databases. This way, you can ensure that customer records are clean and communication outcomes are better.
Why Is Phone Validation Crucial?
Throughout a customer's lifecycle, a phone number is generally the primary mode of interaction between a business and the customer. Hence, enhancing phone data quality has multiple perks:
Better Customer Communication
When phone numbers are incorrect, you cannot reach customers when it's most required. You cannot share appointment reminders, delivery and payment notifications, security alerts, or marketing campaigns. But through validation, your communications reach the right recipient. There are fewer undelivered messages or failed calls.
Lower Operational Costs
Resources are wasted whenever you send a text that's not delivered or place an unsuccessful call. While trying to reach customers through invalid phone numbers, your staff ends up wasting precious time too. Simply put, though you spend on SMS campaigns and outbound calls, outcomes are disappointing. Phone number validation, however, can optimize the cost of communication.
Improved Customer Experience
Customers want your communication to be accurate and on time. However, incorrect phone numbers often mean delivery delays, missed appointments, account verification failures, and poor customer support. So, when contact information is precise, your business becomes more responsive and customer trust is strengthened.
Enhanced Data Quality
Over time, customer databases tend to degrade because of:
- Changes in phone number or carrier
- Relocation of customers
- Duplicate records
- Mistakes in data entry
Hence, to make sure your phone data is always dependable, validation is necessary on an ongoing basis. When customer records are cleaner, your analytics will be more accurate as well.
Fraud Prevention
Phone numbers play a key role in digital identity verification. More and more companies are leveraging mobile numbers to send one-time passwords (OTPs), verify new accounts, and support multi-factor authentication (MFA). Mobile numbers are helpful in recovering compromised accounts too.
But nothing works right if phone numbers are fraudulent, disposable, or invalid. Hence, validation is essential. You can spot problematic or suspicious numbers this way, before they are used during authentication or onboarding.
Better Marketing Performance
Open rates with SMS marketing can go up to 98%. Yes, it can be highly engaging. Campaign success, however, depends on the accuracy of your phone numbers. So, how does phone validation help?
- Reduces the number of failed deliveries
- Removes invalid contacts
- Eliminates duplicate records
- Improves segmentation of audience
- Increases efficiency of campaigns
- Boosts personalization by letting you interact through the right channels
Global Customer Operations Support
If you serve customers in different countries, note these challenges associated with international phone numbers:
- National prefixes
- Country codes
- Different plans for numbering
- Variable standards for formatting
Global phone validation can come to your aid, though. It can standardize numbers into formats that are recognized internationally while spotting country-specific details. Hence, you can communicate more consistently across international markets. In fact, cutting-edge verification solutions can work in over 240 countries and territories.
What Happens If You Don't Validate Phone Numbers?
Skipping phone validation usually translates to multiple operational hiccups that keep recurring:
Data Entry Mistakes
When data is entered manually, common errors like incorrect formatting, absent country codes, and transposed digits crop up. Luckily, validation in real time can detect these mistakes before they infiltrate customer databases.
Duplicate Customer Records
Customers might use different phone formats to register more than once. Detecting duplicates is, however, easy when you standardize phone numbers. This means overall database quality improves.
Decay of Databases
It's not uncommon for customers to replace mobile numbers, change providers, or disconnect old services over time. In other words, phone numbers often become obsolete. With regular validation, though, you can keep customer information up to date.
Compliance Risks
Depending on your industry type, it might be necessary to use mobile numbers for authenticating customers, managing consent, and handling regulatory communications. To make sure you go about these tasks effectively, it's vital to maintain accurate phone data.
What Best Practises Should Be Followed for Phone Validation?
It's best to adopt these practices and integrate phone validation with broader processes revolving around data quality:
Validate at Entry Points
Note where customers enter their phone numbers for the first time, be it on an online form, CRM system, or application. Ensure phone numbers are verified at such entry points. Validation in real time means you won't have to put in as much effort toward downstream corrections.
Cleanse Databases Regularly
Even after onboarding customers, continue with validation. Conduct audits periodically so you can spot inactive, disconnected, or out-of-date phone numbers.
Standardize Formats
Use consistent international formatting to store phone numbers. This will help simplify duplicate identification, integrations, and reporting.
Pair Phone Validation with Other Solutions
Consider integrating phone validation with:
- Identity, address, and email verification
- Data de-duplication
- Customer data matching
These capabilities, when combined, can help you create more trustworthy and complete customer profiles.
Automate Validation Workflows
When validation is automated, customer records are consistently accurate across various systems. And it minimizes human effort. Moreover, as customer databases expand, automation drives scalability.
Capitalize on Phone Validation for Overall Business Success
Phone numbers are much more than mere contact details. No wonder, validation solutions are quickly evolving to offer richer intelligence like geographic insights, live number status, and fraud risk indicators. By validating phone numbers, you can control operational costs, boost authentication and communication, prevent malicious attacks, and engage more with customers.
Hence, the next smart step is to invest in solutions that focus on phone verification and data quality. Validate and standardize phone numbers easily, no matter how large-scale your business. Combine with advanced tools for de-duplication, data matching, identity and address verification, and email validation for truly robust databases.
