Lead verification is the process of confirming that a lead's contact details are accurate and that the person genuinely intended to submit an enquiry. The most common verification methods include SMS verification (sending a code to the consumer's phone that they must enter to complete their submission), email verification, and phone number validation checks.
Why Verification Matters
Without verification, a significant proportion of leads will contain incorrect or fake contact information. Some consumers mistype their phone number. Others enter false details because they want to see pricing information without being contacted. In some cases, bots or fraudulent traffic can generate entirely fake submissions.
For the firm buying those leads, every unverifiable lead is wasted money. You pay for the lead, attempt to call, and reach a dead number or someone who has no idea what you are talking about. This is frustrating, expensive, and entirely preventable with proper verification.
SMS verification is the most effective method for financial services leads because it confirms two things simultaneously: the phone number is real and active, and the consumer is willing to take an extra step to complete their enquiry. That second point is important — it acts as an intent filter. Someone who bothers to check their phone, retrieve a code, and enter it into a form is demonstrably more engaged than someone who fires off a quick form and moves on.
Types of Lead Verification
SMS verification sends a one-time code to the consumer's mobile number. They must enter this code to complete their form submission. This is the gold standard for lead verification because mobile numbers are the primary contact method for most lead follow-up.
Email verification sends a confirmation link to the consumer's email address. While useful for confirming email deliverability, it is less valuable than SMS verification for lead generation because most initial contact happens by phone, not email.
Phone number validation uses database lookups to check whether a phone number is formatted correctly, active, and registered to a real carrier. This catches obvious errors like missing digits or landline numbers submitted as mobiles, but it does not confirm that the person who submitted the form actually owns that number.
Address verification checks the submitted postcode and address against Royal Mail's database. This is useful for geographic targeting but does not directly affect contactability.
The Impact on Contact Rates
The difference in contact rates between verified and unverified leads is substantial. Unverified leads from typical web forms often have contact rates as low as 40-50%. SMS-verified leads consistently achieve contact rates of 60-75%, because the basic problem of wrong numbers has been eliminated before the lead is delivered.
Higher contact rates translate directly into better economics. If you are paying £25 per lead, a 45% contact rate means your effective cost per contact is roughly £56. With SMS verification pushing contact rates to 68%, that same £25 lead gives you an effective cost per contact of around £37. Over hundreds of leads, this difference is significant.
What to Ask Your Lead Provider
When evaluating a lead generation company, ask specifically about their verification process. Do they use SMS verification, email verification, or both? At what stage in the form process does verification occur? What percentage of leads pass verification? A provider who is confident in their verification process will be happy to explain it in detail and share their contact rate data.
Be cautious of providers who claim high-quality leads but cannot explain how they verify contact details. If there is no verification step, you are likely to experience higher refund rates and lower contact rates, which undermines the value of every lead you purchase.
