Most process servers make three to six attempts to deliver court papers before turning to alternatives, though no federal or state law fixes the number. What the law actually requires is due diligence: a reasonable, well-documented effort to find and serve the person. A judge looking at how many attempts a process server made cares far less about the count than about whether those attempts were varied, thoughtful, and recorded. In federal court, the plaintiff has 90 days from filing the complaint to complete service, so every trip needs to earn its place.1Legal Information Institute.

Why Three to Six Is the Common Range
The informal three-to-five-attempt guideline exists because that range, when spread across different times and different days, usually gives a court enough to conclude the server tried hard. It is a working convention among servers and attorneys, not a rule. Two well-timed attempts that establish the address is vacant can demonstrate more diligence than six identical noon visits to the same door.
Servers generally begin at the home address on file, then rotate through weekday mornings, weekday evenings, and a weekend attempt. If the person still isn’t reached, the next moves are workplace visits and any other locations tied to them.
What Makes an Attempt Count
Each attempt has to happen somewhere the person could reasonably be found, usually a home or workplace. Showing up at an address the person left years ago adds nothing to the record. The server also needs to vary the approach: different days of the week, different times of day, weekends included. A Tuesday morning, a Thursday evening, and a Saturday afternoon look very different to a judge than three Monday mornings in a row.
The server documents everything in a sworn affidavit that becomes part of the court file. Date, time, location, and observations all go in. Notes like “lights on but no answer” or “neighbor states subject works night shifts” show the server was paying attention and adjusting the strategy. That affidavit is the evidence a court leans on when deciding whether the plaintiff did enough before asking for an alternative method.
The Due Diligence Standard
Courts deliberately keep due diligence flexible. There is no statute listing steps such as “check a forwarding address” or “knock three times on different days.” A judge reviews what the server actually did and decides whether the effort was thorough given the circumstances.
At a minimum, courts expect the server to confirm the address is current, try the location at varying times and days, and explore other known locations. Showing up at the same house at noon three days running and calling it quits will not satisfy any court. The stronger the affidavit, the easier it is to move on to substituted service or publication when personal delivery fails.
What Changes the Number Needed
The biggest variable is the person being served. Someone with predictable hours at a known address might be served on the first or second try. Someone dodging service may require many more attempts at multiple locations before the server can either complete delivery or build a record strong enough to justify alternatives.
Budget sets a practical ceiling. Standard process service runs roughly $40 to $100 per job, and each extra attempt or new address adds cost. A basic service package limits how many attempts the server can afford to make. Urgent matters like restraining orders sometimes justify tighter, more frequent attempts, though that urgency drives fees higher.
Time is the hard constraint. Federal Rule 4(m) gives the plaintiff 90 days from filing to complete service. Miss that window and the court must either dismiss the case without prejudice or grant an extension, and an extension requires the plaintiff to show good cause.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons State deadlines vary but most impose similar windows. A case handed to a server with a week left on the clock simply cannot support many attempts.
When Someone Refuses or Avoids the Server
Refusing to take the documents does not defeat service. In most jurisdictions, if the server identifies the right person and that person refuses to physically accept the papers, the server can place the documents at their feet. This is commonly called drop service, and courts in the majority of states treat it as valid personal service. The server records the refusal and the manner of delivery in the affidavit, and service is complete.
Active evasion is different. When someone consistently hides, refuses to answer, or gives false information, the server shifts to the workplace, known associates’ addresses, or other locations connected to the individual. Evasion tactics actually help the plaintiff when it comes time to request alternative service, because the affidavit can document a pattern of avoidance that explains why personal delivery failed despite real effort.
What Happens After Failed Attempts
When personal delivery proves impossible despite diligent effort, the plaintiff can ask the court for permission to use a different method. The affidavit of attempts is the primary evidence the judge reviews before granting that request. Without a thorough record of varied attempts, the motion is likely to be denied.
Substituted Service
Federal Rule 4(e) allows leaving copies of the summons and complaint at the individual’s home with someone of suitable age and discretion who lives there.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons The person accepting the documents does not need to be a relative, just a co-resident mature enough to understand the responsibility. Many state rules add a requirement to mail a second copy to the same address after leaving the papers.
Service can also be completed by delivering the documents to an agent the defendant has authorized to accept legal papers. Businesses typically have a registered agent for exactly this purpose.
Service by Publication
When the person’s whereabouts are genuinely unknown, the court may authorize service by publication as a last resort. The plaintiff publishes a legal notice in a newspaper that circulates where the person was last known to be. Publication requirements vary by state, but a common pattern is once per week for several consecutive weeks. Courts only approve this method after the plaintiff shows every other avenue has been exhausted.
If Service Never Gets Completed
Running out the clock has real consequences. In federal court, the judge must dismiss the case without prejudice once the 90-day window closes, unless the plaintiff shows good cause.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons Dismissal without prejudice lets the plaintiff refile, but here is the trap: if the statute of limitations expired while the original case was pending, refiling may be barred entirely. The claim can be lost for good.
That is why servers and attorneys treat service deadlines seriously. A server who senses early that personal delivery will be hard should tell the attorney so an alternative service motion can be prepared before time runs out. Waiting until day 85 to raise a problem leaves almost no room to recover.
What More Attempts Actually Cost
Standard process service typically runs $40 to $100 per job, with a national average around $70. That base fee usually covers an initial set of attempts at a single address. If the person proves hard to find or the server needs to visit multiple locations, expect a surcharge of $20 to $50 on top of the base rate. Same-day or rush service adds another $25 to $50.
Sheriff’s offices also serve civil papers in most jurisdictions, often at lower fees than private servers, though turnaround times tend to be longer because deputies handle service alongside other duties. Fees vary by county and are usually set by local fee schedules rather than any national standard.
When the address itself is unknown or outdated, skip tracing may be needed before attempts even begin. Costs range from about $20 for a basic database search to $350 or more for complex investigations. Getting a quote upfront avoids surprises, since complexity drives the price more than any fixed rate.
