Number validity verification tool evaluation: supports batch identification of empty numbers and risky numbers
In today's increasingly fierce competition in digital marketing and user reach, a core question is becoming more and more obvious: Are the numbers you use really effective? If the list is full of empty accounts, long-term suspended accounts, or high-risk accounts, then no matter how good the channel is, no matter how high-quality the words are, they may come to naught.
Why are number validity verification tools essential?
Whether you are doing mass text messaging, social private domain contact, outbound phone calls or cross-border marketing, the proportion of invalid numbers in the list is often underestimated. But the actual situation shows:
lEmpty accounts, canceled accounts, and long-term downtime accounts will directly lead to failure to reach and waste of resources.
lUsing a high proportion of invalid accounts to send will reduce the reputation of the sending platform, and may even result in account bans or traffic restrictions.
lRisk accounts (such as frequent complaints, abnormal registration, association bans, etc.) may trigger account bans or channel blacklists.
So before actually executing your marketing, useThe "Number Validity Verification Tool" list cleaning has become a preparatory action to improve operational efficiency and reduce risk costs.
What key dimensions did we measure?
After comparing multiple number verification tools, we focused on the following key dimensions for evaluation:
lBatch processing capability: How many numbers are supported to be uploaded (10K, 50K, 100K+), what is the processing time.
lEmpty number recognition accuracy: Can it accurately identify empty numbers and canceled numbers?
lRisk number detection capability: Whether it can identify high-risk numbers (such as blocked accounts, high complaint rates, virtual cards, etc.).
lMultidimensional status return: Whether to return fields including whether to register, power on and off status, social platform registration status, etc.
lExport and system docking capabilities: Whether to support formatted export,API docking, freely embedded in the marketing process.
lGlobal coverage: Whether to support multiple countries, multiple operators, and cross-language number segments.
Summary of actual measurement results
Among the many tools we selected, afterAfter testing 30,000 numbers from the United States, India, Indonesia, the Philippines and other countries, the following summary was drawn (represented by "Tool A", the real name is omitted):
ltoolA To upload 100,000 numbers in batches, the processing time is about 8 minutes.
lexist Among the 30,000 numbers, Tool A identified about 32% empty numbers and 2% high-risk numbers (high frequency of complaints or account bans).
lThe export report contains fields: number, country, status (real number/empty account/deactivated), whether WhatsApp is registered, and risk score.
lThe accuracy of risk number identification relies on historical data, and some virtual cards have still not been identified.
lThe multi-country test coverage is good, and the deviation of the empty number recognition rate in India and Indonesia is slightly higher (approximately36%).

The following are recommended key points to consider when choosing a tool:
lTarget countries are given priority: Where is your main marketing area? Prioritize tools that have good carrier coverage in the country.
lBatch threshold and timeliness: Whether to support batch More than 100,000? Is the detection time within an acceptable range?
lRisk identification ability: In addition to empty numbers, whether the tool pays attention to"Risk number"? For example, there are many complaints, historical account bans, virtual cards, etc.
lResult Flexibility: Is there an export function, clear field definitions, and can it be directlyUsed in CRM/outbound call system?
lInterfaces and automation: If you have an automated process, does it support API concatenation?
lCost and value for money: Compared with pure empty account identification, tools with risk detection and social platform registration identification will cost more but have greater returns.

lDuring the same period, the reach failure rate dropped to approximately 12%.
