Creating multiple accounts on advertising platforms, social networks, or e-commerce sites has never been more challenging. In 2026, anti-fraud systems instantly flag suspicious behavior: mismatched GEO between IP and phone number, sudden IP changes during verification, or shared fingerprints across accounts. The result? Instant bans, lost budgets, and wasted time.

The proven solution used by experienced affiliate marketers is simple: establish the digital Triad of Trust by combining high-quality virtual numbers with reliable residential proxies. In this guide, we’ll show exactly how secondnumber and Mango Proxy work together to create a cohesive digital profile that survives the most rigorous anti-fraud checks.

Why account registration requires extra protection in 2026

Platforms have significantly strengthened their verification rules over the past year:

• Phone verification is now mandatory almost everywhere (Facebook, Google Ads, TikTok Ads, etc.)

• Multi-accounting detection algorithms react to the slightest inconsistency in seconds

• Critical GEO mismatch: Any inconsistency between the IP address and the phone number’s country is an immediate red flag that triggers anti-fraud systems

• Reused numbers, SIM cards with spam history, and shared datacenter IPs are blacklisted faster than ever

Without proper protection, even a single registration attempt can burn an entire IP range and ruin your farming setup for weeks.

What Second Number is and why affiliates rely on it

secondnumber.io provides virtual phone numbers specifically designed for online verification. These numbers receive SMS codes instantly and work with hundreds of platforms — from major ad networks to marketplaces and social media.

This makes Second Number a convenient tool for affiliates, marketers, and teams working with bulk registrations and account testing.

Unlike physical SIM cards, virtual numbers do not require hardware, are easy to scale, and allow instant receipt of verification codes without delays. This is especially important for affiliates who need to quickly launch and warm up accounts, bypass regional restrictions, and reduce the risk of bans.

Affiliates rely on Second Number because the service:

• Provides fast and reliable SMS delivery with API support

• Supports hundreds of platforms and services

• Allows safe account creation without using personal phone numbers

• Helps manage multiple accounts efficiently

• Saves time and operational costs compared to traditional SIM solutions

As a result, Second Number becomes a critical infrastructure tool for affiliates focused on speed, scalability, and account stability.

How virtual numbers work for SMS verification

You select a number from the desired country, use it during registration, receive the verification code in your secondnumber dashboard, and complete the signup. The number is temporary (one-time use), so you can receive only 1 sms on 1 number

How to get a number

1) Register on a secondnumber service by using your email

2) top up your balance using crypto or Alipay

3) Choose service that you want to register, if you don't see service that you need, you can try "Any Other" option

4) Buy number, turn on VPN with and match the location of the number that you bought it will increase chanses of registration

5) Get SMS and complete registration

The difference between virtual numbers and traditional SIM cards

Physical SIM cards are expensive, slow to replace, and often tied to real personal data. Virtual numbers are instant, disposable when needed, and leave no trace to your identity — perfect for high-volume account creation.

Key use cases for affiliate marketers and multi-account setups

• Creating dozens of ad accounts for campaign testing

• Managing multiple social media profiles without cross-bans

• Safe registration on platforms with strict phone verification policies

Why proxies are essential when using virtual numbers

A virtual number alone is not enough. If your IP address doesn’t match the number’s country or changes mid-process, the platform immediately flags the profile due to a broken logic chain.

Matching IP GEO with the numbers country to avoid bans

When you use a US virtual number, your traffic must come from a real US residential IP. Any mismatch triggers anti-fraud systems.

Isolating accounts to prevent cross-linking and fingerprint leaks

Each account must reside on its own dedicated IP. Aggressively rotating or shared IPs create overlapping digital fingerprints that platforms use to connect and mass-ban related accounts.

Reducing anti-fraud triggers with clean, stable IP addresses

Residential proxies from real ISPs have high trust scores and rarely appear on blacklists — unlike cheap datacenter IPs that get blocked within hours.

Choosing the right type of proxy for safe account creation

For account registration and farming, residential (or ISP) proxies are the gold standard. They behave like real user connections and maintain stability during long sessions.

How to combine secondnumber.io and Mango Proxy for safe account creation

Here’s the exact workflow top teams use:

Step-by-step workflow for secure registration

1. Choose a proxy with strict GEO matching to your secondnumber (e.g., USA residential IP for a US number). This eliminates the weakest link in your setup

2. Configure the proxy in your anti-detect browser (Dolphin, AdsPower, Octo Browser, etc.)

3. Purchase and activate the virtual number in secondnumber dashboard

4. Open the target platform through the proxy and complete registration

5. Use the same IP + number combination for future logins and password recovery

Why Mango Proxy improves your account survival rate

• Over 90 million real residential IPs across 200+ countries

• Precise city and ASN-level targeting to match any secondnumber perfectly

• Extremely low ban rates thanks to clean, ethically sourced IPs

• Sticky sessions up to 120 minutes — ideal for verification flows

• Seamless integration with all popular anti-detect browsers

Teams using Mango Proxy report 3–5x longer account lifetimes compared to standard datacenter solutions.

Best practices for scaling accounts safely

• One IP per account — always. Never reuse the same proxy across multiple accounts on the same platform

• Avoid switching IPs during verification. Changing IP mid-process is one of the fastest ways to trigger a permanent ban

• The phone country must perfectly match your proxy, billing details, and targeting settings. Any mismatch in this triad (Phone GEO – IP GEO – Fingerprint GEO) is one of the fastest and most common ban triggers in 2026

• Choose long-term virtual numbers for farming accounts. Short-lived numbers work for testing, but farmed accounts need rented numbers that stay active for months

• Never change the phone number on a live, spending account — it looks exactly like Account Takeover (ATO) fraud to Meta, Google, and TikTok

• Keep device fingerprints consistent across sessions. Use the same browser profile, proxy, and virtual number combination every time you log in

Final thoughts: building a safe workflow for long-term scaling

Virtual numbers from secondnumber solve the SMS verification hurdle, while high-trust residential proxies close the last gap in the digital Triad of Trust (Phone GEO, IP GEO Fingerprint GEO). Together they let you create, warm, and scale accounts that platforms simply can’t flag.

To make the transition even easier, the Mango Proxy team has prepared a special offer exclusively for the secondnumber.io community.
