Here are SiteID and 1Lookup side by side on the terms you check before you sign.

Questions

People ask these questions before they switch from SiteID.

What is the best SiteID alternative?

If you need consumer identities with a verified phone and a cleaned postal address, at agency scale, SiteID is built for that: SiteID sells packages of up to 60 pixels, the Agency one white-label. If you want the individual person as data, by API, webhook or CSV, at 5 credits per person on a balance that also pays for phone, email and IP lookups, 1Lookup's Website Visitor ID is the alternative. Website Visitor ID requires approval. Start the 7-day free trial, then send the short application inside your account: we review each website before we switch on visitor identification.

How much does SiteID cost?

Packages of pixels, each including 4,000 resolved identities a month, on a three-month commitment: SMB, Pro and Growth print identity counts, and Broker and Agency print a price only. Checked October 2026 on siteid.ai.

How much does 1Lookup charge for an identified visitor?

5 credits for each identified person, and nothing for a visitor who is not identified. Starter ($99 a month) covers up to 4,000 identified people at $0.02475 each, Growth ($299 a month) covers up to 17,000 identified people at $0.0176 each, Professional ($799 a month) covers up to 50,000 identified people at $0.016 each and Enterprise ($1,999 a month) covers up to 200,000 identified people at $0.01 each. Credits come from a plan that also pays for every other 1Lookup product, and unused subscription credits roll over for up to 3 months.

Is 1Lookup cheaper than SiteID?

On month-to-month billing 1Lookup costs less at 1 to 40,000 people a month. SiteID never costs less than a 1Lookup plan in its published range. At 4,000 identified people a month, 1Lookup Starter costs $99 and SiteID SMB costs $4,800. At 12,000 identified people a month, 1Lookup Growth costs $299 and SiteID Pro costs $6,700.

Does SiteID identify people or companies?

People: SiteID resolves US consumer and B2B visitors to identities with a verified email and phone, 4,000 a month per pixel.

Which visitors does 1Lookup identify?

Website Visitor ID identifies visitors worldwide outside Europe: every country except the European Union, Iceland, Liechtenstein, Norway, the United Kingdom and Switzerland. A visitor it cannot identify, wherever they are, costs no credits, because only identified people are billed.

What comes back for each identified person?

Identified people come back by API, by webhook or in a CSV file, each with a name, a work email, a LinkedIn profile URL, a job title and a company, and a phone number with its do-not-call flag for about 1 in 4 people.

Do unused credits carry over?

1Lookup subscription credits roll over for up to 3 months, so a quiet month does not waste a plan.

How do I switch from SiteID to 1Lookup?

Add one script to the pages where you want visitors identified, and pick where the people go: an API, a webhook or a CSV. SiteID runs on a three-month commitment, so start the 1Lookup trial a month before your term ends and compare the two side by side. Run SiteID and Website Visitor ID side by side for a month and compare the named people you get before you cancel anything.

Is SiteID worth it in 2026?

Yes, if you need US consumer and B2B identities with a verified email, a phone and an NCOA-cleaned address, and you can commit to three months at $4,800 or more a month. If you want a named person with a work email for each identified visitor, from $99 a month for 4,000 identified people, compare 1Lookup.
