(Question) About Instagram account generating

GaSXV2 · 15.01.2026

Hi everyone,

I'm automating Instagram account creation via their web API, but hitting a wall. Immediately after account creation, Instagram redirects to SMS verification page (suspend/phone verification).

My setup:

Instagram web API account creation
Residential rotating proxies (3-minute sticky IPs) (I used a Turkish-located proxy because I was creating a Turkish account.)
FirstMail for email verification
Real mobile User-Agents

Python:

MOBILE_USER_AGENTS = [

Instagram-format Device IDs

Python:

    def _generate_exact_instagram_device_id(self) -> str:
        """'aWxxxxALxxxbekbi-xxx0Vx4_Ju4'"""
        chars = string.ascii_letters + string.digits
        part1_first = random.choice(string.ascii_lowercase)
        part1_rest = ''.join(random.choices(chars, k=15))
        part1 = part1_first + part1_rest
        part2 = ''.join(random.choices(chars, k=9))
        part3 = ''.join(random.choices(chars, k=4))
        device_id = f"{part1}-{part2}_{part3}"
        if len(device_id) != 30:
            if len(device_id) > 30:
                device_id = device_id[:30]
            else:
                missing = 30 - len(device_id)
                part3 += ''.join(random.choices(chars, k=missing))
                device_id = f"{part1}-{part2}_{part3}"
                device_id = device_id[:30] 
        return device_id

And using chrome120

The exact issue:

Account creates successfully
Gets redirected to: instagram.com/accounts/suspended/?next=https%3A%2F%2Fwww.instagram.com%2Faccounts%2Fonetap%2F%3F__coig_ufac%3D1#
Page shows: "Confirm it's you" with SMS verification requirement
Account is effectively suspended until phone verification

What I've tried:

Various delays between actions
Multiple country IPs
Realistic browser fingerprints

Questions:

What specific signals trigger this immediate SMS challenge?
Is it Device ID related? Header patterns? Proxy reputation?
How are successful automation tools bypassing this in 2026?
Any working solutions or patterns?
