How to Use USPS Bulk Mailing Services Near Me

Whether your business is small or large, you can save a lot of postage with bulk mailing services near me. USPS offers discounts on a wide variety of commercial and non-profit mail based on size, destination and other factors. But it can be complicated. You’ll need a permit, special stamps (not your ordinary postage stamps), a postage meter or an approved permit imprint. Then you’ll need to prepare your mail according to USPS sorting and packaging requirements.

For example, you’ll need to rubber-band or bundle letter-sized pieces together and then arrange them in trays or sacks to qualify for lower USPS postage rates. This is called “presorting.” You’ll also need to prepare a complete mailing list and verify that the addresses are valid. And then there are rules about printing a barcode on each piece. You’ll also need to print paperwork for submission and label each container with the postal codes required by USPS.

Some kinds of mailings are easier to do than others. For example, if you’re a small local business, you can use Every Door Direct Mail to reach all the residential and business mailboxes in your area for a very low price. But even this kind of bulk mailing requires a permit and the right mailing list. You’ll also need to follow strict presorting guidelines, which can be time consuming. USPS address validation is a good way to ensure the accuracy of your mailing list and get the best rates on your mail.

Send Postcards Online India

Postcards are a beautiful way to express your sentiments to someone. They are more personal and meaningful compared to the impersonal and distant digital communication via gadgets like smartphones or laptops. Moreover, handwriting is also a form of art that can be appreciated by others. You can use a postcard to send a message or share an image. This is especially true if you are travelling to another country. Here are some tips for writing a postcard that your recipient will love to read:

Write a personal message in readable handwriting. Include the destination and address of the receiver on the postcard and the postage stamps (preferably with the year mentioned) on it. You can also ask your post office to get a special cancellation for the postcard. This will make your postcard more appealing and will also introduce the receiver to philately (stamp collecting).

Sending a postcard is an inexpensive and convenient way to communicate. It is also a great way to reconnect with friends and family. You can find a postcard in any shop that sells stationery or at the post office. Make sure you write the correct address and PIN code on the postcard. The postal department will dispatch the postcard to its destination within India.

This week had some small regressions that did not warrant further investigation, several of which were dismissed as being noise/blips in the data. There were also a number of gains. (Don't get exicited about that 20.6% improvement, its an measurement artifact from a temporary blip in the PR that immediately preceded this week's triage.)

Triage done by @pnkfelix. Revision range: 76101eec..f9c2421a

3 Regressions, 5 Improvements, 5 Mixed; 3 of them in rollups 55 artifact comparisons made in total

A Complete Guide to Understanding the ZIP+4 Code Database

The United States Postal Service while delivering mail depends on more than just the 5 digits ZIP code. This use helps them to deliver the mails accurately and efficiently. They depend on ZIP Plus 4 database. This database adds more layers of information that helps businesses and organizations to enhance delivery rates, decrease cost and improve satisfaction of customers. However, it is wise to know what this database is and why it is critical for businesses to use it. 

What Is a ZIP Plus 4 Code?

There are 9 digits in this database and is in constant use by USPS to accurately identify a delivery location. The initial 5 digits is the normal ZIP code; however, the remaining 4digits let one know about information like city block, group of apartment, particular building or even a mailbox. 

For example, the ZIP Code 90210 might apply to a general area in Beverly Hills, but 90210-1234 might refer to a specific office floor within a commercial complex. This level of accuracy significantly reduces errors and improves mail sorting and delivery efficiency.

What Is the ZIP Plus 4 Database?

This database is a comprehensive dataset maintained by USPS that contains all ZIP+4 Codes currently in use, along with related address information. It is made available through USPS-certified vendors and is updated frequently to reflect new addresses, removed codes, or boundary changes.

The database typically includes:

Full ZIP+4 Codes

Street address ranges

City and state names

County names

Delivery point details

Carrier route numbers

This data can be delivered in formats like CSV, SQL, or through an API, depending on the vendor and intended use.

Why Is It Important for Businesses?

Businesses rely on this database for a variety of operational and marketing functions:

Address validation: Ensure that customer addresses are deliverable and formatted correctly.

Mailing discounts: Qualify for USPS bulk and automation postage discounts.

Delivery efficiency: Speed up order fulfillment and reduce returned mail.

Targeted marketing: Combine ZIP+4 data with demographic information for precise campaign targeting.

Where Can You Get the ZIP Plus 4 Database?

While USPS does not offer this database directly for public download, it licenses the data to certified vendors. These providers offer monthly or weekly updates and additional tools for integrating the data into your business systems.

The ZIP Plus 4 Database from ZIP-Codes.Com plays a critical role in modern address management. Whether you're a small business trying to send mail efficiently or a large enterprise running complex logistics or marketing operations, this database provides the accuracy and reliability you need. Investing in ZIP+4 data is a smart move for any organization looking to optimize delivery, reduce costs, and stay compliant with USPS mailing standards. Call 1 800 425 1169 to purchase and download this database. They make it possible to have the latest dataset.

JavaScript Check If Key Exists in Object: A Complete Guide

When working with objects in JavaScript, one of the most common tasks is checking whether a certain key or property exists. This is essential for writing robust, bug-free code—especially when dealing with dynamic data structures, APIs, or user input.

In this guide, we’ll walk through different ways to perform a JavaScript check if key exists in an object. We'll cover both traditional and modern techniques, highlight edge cases, and explain when to use each method.

For a step-by-step breakdown with code examples, check the full guide here: JavaScript Check If Key Exists in Object

What Is an Object in JavaScript?

Before we dive into how to check for keys, let’s clarify what an object is in JavaScript.

An object in JavaScript is a collection of key-value pairs, where keys (also known as properties) are strings or symbols, and values can be anything—numbers, strings, arrays, functions, or other objects.

javascript

CopyEdit

const user = {

  name: "Alice",

  age: 30,

  email: "alice@example.com"

};

In the example above, name, age, and email are all keys of the user object. Now let’s explore how to check if a key like "email" exists.

1. Using the in Operator

The in operator is the most direct way to check whether a key exists in an object—even if its value is undefined.

javascript

CopyEdit

"email" in user;  // true

"phone" in user;  // false

Pros:

Works even if the value is undefined

Checks both own properties and inherited ones

Cons:

Might return true for inherited keys if you're checking a prototype-based object

2. Using hasOwnProperty()

The hasOwnProperty() method checks only the object’s own keys—not those inherited from the prototype chain. This makes it a safer alternative in many scenarios.

javascript

CopyEdit

user.hasOwnProperty("email"); // true

user.hasOwnProperty("toString"); // false (inherited from Object.prototype)

Pros:

More accurate if you care only about "own" properties

Prevents false positives from prototype

Cons:

Slightly more verbose

Can throw an error if the object is null or undefined

3. Using Optional Chaining (?.)

If you just want to safely access a key without causing an error, optional chaining is a clean and modern way.

javascript

CopyEdit

const city = user?.address?.city;

This won’t throw an error even if address doesn’t exist. However, optional chaining is not a direct key-existence check—it’s for safe access, not verification.

4. Comparing typeof obj[key] !== "undefined"

Another way to verify key existence is to check whether its value is not undefined.

javascript

CopyEdit

if (typeof user["email"] !== "undefined") {

  console.log("Email exists");

}

Warning:

This method fails when the key exists but its value is literally undefined.

javascript

CopyEdit

const data = { info: undefined };

"info" in data;               // true

typeof data.info !== "undefined"; // false (but key exists)

5. Using Object.keys() or Object.hasOwn()

Modern JavaScript (ES2022+) introduces a new method:

javascript

CopyEdit

Object.hasOwn(user, "email"); // true

This method is functionally similar to hasOwnProperty() but works more reliably across edge cases and is not affected by overriding.

6. With Object.keys() and includes()

This is more verbose but also useful in array-centric workflows:

javascript

CopyEdit

Object.keys(user).includes("email"); // true

This returns an array of the object’s own property names and checks for existence.

Edge Cases to Consider

1. Value Is undefined

You might get tripped up if a key is set to undefined:

javascript

CopyEdit

const config = { timeout: undefined };

"timeout" in config; // true

typeof config.timeout !== "undefined"; // false

2. Object Is null or undefined

Always ensure your object is valid before checking keys.

javascript

CopyEdit

const settings = null;

settings && "theme" in settings; // safe

Practical Example: Validating API Response

Let’s say you’re working with a JSON API response:

javascript

CopyEdit

const response = {

  status: 200,

  data: {

    user: {

      id: 123,

      name: "John"

    }

  }

};

if ("user" in response.data) {

  console.log("User info received");

}

Checking the presence of a key like "user" before accessing it can prevent runtime errors.

Best Practices

✅ Use hasOwnProperty() or Object.hasOwn() when checking for own properties.

✅ Use in when you need to check both own and inherited properties.

❌ Avoid typeof obj[key] !== "undefined" for critical checks.

✅ Use optional chaining (?.) for safe access—but not for explicit key checking.

✅ Always validate the object before accessing or checking keys.

Conclusion

Whether you’re debugging code, validating API data, or simply writing safer JavaScript, knowing how to check if a key exists in an object is a fundamental skill. JavaScript gives you multiple tools to handle this, and each has its pros and cons depending on your use case. Want more examples and deep dives?
