Essential Documents for Opening Advertising Accounts: A Practical Guide to BIGO Ads, KWAI, MediaGo, popIn, Mintegral, and Moloco

In the wave of digital marketing, advertising has become a core strategy for businesses to acquire users, build brand awareness, and boost sales. To run campaigns smoothly on major social media and programmatic advertising platforms, the very first step is to open an advertising account.

For many businesses, however, account opening is far from a simple “register + top-up” process. Each platform has its own requirements for documentation, qualifications, and review standards. Without proper preparation, companies may face rejected applications, delayed campaigns, or even permanent account suspension.

As a company specializing in advertising account opening and digital marketing, Novabeyond has helped over 500 businesses successfully open and operate ad accounts across leading global platforms, including BIGO Ads, KWAI, MediaGo, popIn, Mintegral, and Moloco. In this article, we will break down the essential documents required for account opening, key process considerations, and how to improve your approval rate on the first attempt.

Why Is Opening an Advertising Account So Important?

An advertising account is not only the entry point for campaign delivery but also the core tool for data analysis, budget control, and audience management.

A stable and long-term ad account helps businesses achieve the following goals:

● Reach target users quickly: Deliver ads based on location, interests, and behaviors with precision.

● Flexible budget control: Adjust spending daily, weekly, or monthly.

● Accumulate valuable advertising data: Build more accurate audience models over time.

● Reduce advertising costs: High-quality accounts minimize wasted impressions and ineffective exposure.

On the other hand, if an account application fails or is suspended, it can disrupt ad campaigns and even block a brand’s expansion into target markets.

Comparison of Documentation Requirements Across Advertising Platforms

Tip: If you are an agency running ads for another brand, make sure to prepare a brand authorization letter; otherwise, your application is likely to be rejected.

Essential Documents Checklist for Opening a Business Advertising Account

To increase your chances of getting your account approved on the first attempt, it is recommended to prepare the following documents in advance:

1. Company Documentation

• Valid and up-to-date business license (scan / PDF)

• Tax registration certificate (required by some platforms)

• Company website (ensure content aligns with the advertising industry)

2. Legal Representative Information

• Contact details (phone number & email)

3. Advertiser Information

• Advertising plan (target audience, budget, campaign duration)

• Product or service introduction (text + images)

• Landing page URL (content must be compliant)

4. Additional Supporting Documents (depending on platform requirements)

• Brand authorization letter (required for agency promotion)

• App download link (if promoting an app)

• Third-party certifications (required for regulated industries such as healthcare or education)

Common Issues in Advertising Account Opening & Case Studies

Case 1: Rejection Due to Inconsistent Information

A cross-border e-commerce company submitted a website whose industry did not match the business license (license stated “technical services,” but the website sold cosmetics), resulting in KWAI rejecting the application.

Solution: Optimize the website content to align with the business license and provide additional industry-related documents before submission.

Case 2: Account Suspension Due to Early-Stage Violations

A gaming company expanding overseas successfully opened an account on BIGO Ads, but its ad creatives contained exaggerated earnings claims. The platform flagged this as a violation and immediately suspended the account.

Solution: Conduct compliance review before launching campaigns to avoid violating advertising laws and platform policies.

Case 3: Missing Brand Authorization Letter

An agency applying for a MediaGo ad account failed to provide a brand authorization letter for the client they were promoting, resulting in application rejection.

Solution: Sign an authorization agreement with the brand in advance and ensure it is officially stamped.

5 Key Tips to Improve Advertising Account Approval Rate

1. Ensure complete and accurate documentation: Any false or vague information increases the risk of rejection.
2. Prepare a precise advertising plan: Clearly define your target audience, budget, and campaign duration to help the platform quickly assess compliance.
3. Conduct a compliance check in advance: Review landing pages, ad creatives, and copywriting to ensure adherence to platform policies
4. Use an official company email for application: This improves the platform’s trust in the business’s authenticity
5. Choose an experienced third-party agency: Agencies can help avoid common mistakes and often have dedicated “fast-track” channels with platforms, speeding up the approval process.

Advantages of Using a Third-Party Agency to Open Advertising Accounts

● While businesses can apply for ad accounts on their own, partnering with a third-party agency like Novabeyond can save significant time and reduce trial-and-error costs:

● Faster approval: Agencies often have internal channels, speeding up the review process by 30%–50% on average.

● Higher first-time approval rate: Minimizes rejections caused by incomplete documentation or industry restrictions.

● Compliance risk management: Agencies review your ad content in advance to ensure adherence to platform policies.

● One-stop multi-platform account opening: Avoid submitting documents repeatedly for different platforms.

● Campaign strategy support: Full-cycle service from account setup to campaign optimization.

Conclusion

Successfully opening an advertising account is the first step for businesses to run global campaigns efficiently. Whether you choose to apply on your own or work with an agency, it is essential to prepare complete documentation in advance and ensure compliance and consistency.
