7 Critical Secrets To Maximizing Your Uma Musume Friend ID In 2025: The Ultimate Tier List For Borrowing Support Cards

The Uma Musume Friend ID is arguably the single most important, yet often overlooked, mechanic for any serious trainer in Uma Musume Pretty Derby. As of December 17, 2025, the meta continues to shift with new scenarios and powerful Support Cards, making the strategic use of your Friend ID more vital than ever for achieving S+ and U-Rank Uma Musume. This seemingly simple 9-digit code is the key to bypassing the gacha grind and instantly accessing Max Limit Break (MLB) SSR cards that your own account may lack.

To consistently produce top-tier Uma Musume, you must leverage the community to borrow high-level resources. Whether you are looking for the latest Speed card like Kitasan Black or a specific set of Inheritance Factors, knowing where and how to share your Trainer ID is essential. This comprehensive guide breaks down the current meta, the most desirable cards to borrow, and the best community hubs for a successful Friend ID exchange.

The 2025 Uma Musume Friend ID: Your Gateway to Max Limit Break (MLB) Power

The core function of the Friend ID system is to allow trainers to borrow a single Support Card from another player's roster for each training run. This borrowed card functions exactly as if it were your own, but crucially, it is almost always a Max Limit Break (MLB) version. A non-MLB SSR card is vastly inferior to an MLB version, as the final limit break unlocks game-changing stat bonuses, skill hints, and specialized training effects.

By adding friends who specialize in different areas—Speed, Stamina, Power, Guts, or Intelligence—you ensure you always have the perfect resource for any training scenario, whether it's the classic URA Finals, the Aoharu Cup, or the latest scenario update from Cygames.

Current Must-Borrow Support Card Tier List (Late 2025 Meta)

The most sought-after Friend IDs are those that consistently feature Max Limit Break copies of the current meta-defining Support Cards. If you own and share any of these, your Friend ID will be in high demand. If you are the one borrowing, these are the cards you should prioritize searching for. This list is based on the latest Japanese server updates and their imminent arrival on the Global server.

• SSR [Fire at My Heels] Kitasan Black (Speed): Still the undisputed king of Speed support. Kitasan Black offers superior training efficiency, high-level skill hints, and a massive initial bond, making it a non-negotiable borrow for almost all UMA builds.
• SSR [Wave of Gratitude] Fine Motion (Intelligence): A top-tier Intelligence card that provides excellent stat gains and a highly valuable recovery skill. Fine Motion is a cornerstone for any build that relies on high Intelligence for race positioning and fatigue management.
• SSR [Peace of Mind] Super Creek (Stamina): Essential for long-distance (Long/L) and medium-distance (M) builds. Super Creek provides a powerful recovery skill and great Stamina bonuses, often saving a run from a critical stamina failure.
• SSR [The Setting Sun and Rising Stars] Special Week (Speed/Power): A versatile card, often used when trainers need a balance of Speed and Power gains. Her unique events and high base stats make her a reliable choice for many training styles.
• SSR [Double Carrot Punch!] Biko Pegasus (Speed): A strong alternative or second Speed card, Biko Pegasus offers excellent training value, especially in scenarios that favor multiple Speed training sessions.

How to Find and Share Your Trainer ID (and Why You Should)

Finding your own Trainer ID is the first step to leveraging the community. This unique 9-digit code is what other players use to send you a Friend Request. Sharing it strategically is the best way to ensure you get a steady stream of Friend Points.

Step-by-Step: Locating Your Uma Musume Trainer ID

1. From the main screen (Home), tap the Menu (メニュー) button, usually located in the bottom right corner.
2. Select the Friends (フレンド) tab.
3. Your 9-digit Trainer ID (トレーナーID) will be prominently displayed at the top of the screen.
4. To add another player, select the ID Search (ID検索) button and input their code.

The Hidden Currency: Friend Points and Their Value

Every time a player borrows your Support Card, you earn Friend Points (フレンドポイント). These points accumulate quickly if you are sharing a highly desirable MLB card, and they are not just for show. Friend Points act as a crucial in-game currency.

You can exchange Friend Points in the Shop for valuable items, including:

• Awakening Materials: Necessary for leveling up your Uma Musume's unique skills.
• Support Card Limit Break Items: Essential for reaching MLB status on your own cards.
• Limited-Time Items: Occasionally, the shop offers rare items or consumables that can significantly boost your training.

The Ultimate Guide to Friend ID Exchange Hubs

Simply having a great card isn't enough; you must promote your Trainer ID where other serious players are looking. The community for Uma Musume Pretty Derby is global and highly organized, using several key platforms for ID exchange.

1. Dedicated Community Threads (Reddit & Steam)

The most active and current hubs for Friend ID exchange are often found on social platforms. The official r/UmamusumeGame Reddit community and the Steam Community discussions are constantly updated with threads dedicated solely to sharing IDs.

• Best Practice: When posting your ID, always include the card you are sharing (e.g., "MLB Kitasan Black, Speed 1200") and a brief note about your focus (e.g., "Looking for MLB Fine Motion" or "Focusing on Long Distance Factors").

2. The Advanced Trainer's Tool: Umamusume DB

For trainers focused on competitive play and specific builds, general friend lists are often too slow. The secret weapon is using specialized databases like Umamusume DB.

• Factor Search: These sites allow you to search for Friend IDs based not only on the shared Support Card but also on the Inheritance Factors of the Uma Musume parent. This is critical for finding parents with high-star Speed, Power, or specific distance/ground aptitude factors, which are essential for breeding top-tier competitors.

3. Club ID vs. Friend ID: Understanding the Difference

While often confused, the Club ID (for joining a Trainer Club) and the Friend ID (for borrowing Support Cards) serve different purposes. Joining an active club is highly recommended, as it provides separate benefits like Club Points and access to club-exclusive events. However, your Friend ID is the one that directly impacts your daily training efficiency by providing the critical MLB Support Cards you need. Make sure to share both, but prioritize the Friend ID for immediate training gains.

Final Secrets to Optimal Friend ID Management

To maintain a high-quality friend list and ensure you are always borrowing the best resources, follow these advanced tips:

• Clear Inactive Friends: Periodically review your friends list and remove players who have not logged in for several days or who are sharing outdated/non-MLB Support Cards. This frees up space for new, active trainers with meta-relevant cards.
• Check Factors Daily: Even if a friend is sharing a good Support Card, their Uma Musume Parent may have highly desirable Inheritance Factors that change daily. Always check the factors before starting a new training run, as a 3-star Speed factor is a huge bonus.
• Focus on MLB: Never borrow a Support Card that is not Max Limit Break (MLB). The difference in performance between an MLB card and a 0-Limit Break card is massive and will severely limit your Uma Musume's potential.

By actively managing your Friend ID, sharing a relevant MLB card, and strategically searching the community for the latest meta cards like Kitasan Black and Fine Motion, you can overcome the gacha barrier and consistently produce powerful Uma Musume, ensuring your success in Pretty Derby throughout 2025 and beyond.
