Another method I will mention is using a paid service. Using these online paid tools may bring your more detailed information on the email addresses gathered with quality data. One example of this would be a site like CoCoFinder They have both free and paid services. People would use services like cocofinder to perhaps dig out more information on their customers, who purchases, their buying habits etc. - Source: dev.to / over 1 year ago

At the national level that may be true but it does not seem to be that way at the state level. Many of the states listed on e-verify.gov's site are politcally red. Further digging showed that all nine states that require ALL businesses to use E-Verify are "red" states and many of those that have local (county/city) ordinances that require E-Verify are "red" states.

In any case, can I just submit the employer name as it is listed on e-verify.gov since I don't have a number? I have worked for this company for 9 mo now, so I should be able to extend, no? Source: over 1 year ago

I'm not sure on the details of how it's done ... But it certainly is done :) Honestly, the library/libraries used are kinda moot - those things change all the time (ie, it doesn't matter if it's OpenCV or something else) Most government-issued IDs are intentionally designed to be very hard to OCR (it's why they have barcodes/etc on them for automated scanning) - and any advances in image processing... - Source: Hacker News / almost 3 years ago
